Volcanic Eruptions Types of Volcanoes Associated Lava and Geology

What is a volcano? Volcanoes are planetary vents, that emit heated gases along with molten rocks and fragmented rock pieces. Eruptions can occur from these volcanic vents, causing strong displays of power within the planet as well as spewing out said rocks and gases. While majorly destructive, volcanoes are a necessary environmental occurrence, which allows the release of heat and gases that would be otherwise trapped within the planet. These vents are a needed and natural process from resulting thermal […]

The Boxing Day Tsunami

December 26, 2004 a tragedy happened in Thailand that will never be forgotten. At about 8:00 o’clock in the morning when a 9.1 earthquake happened. For about 7 hours waves were building up and traveling to the costal area and hit the island Phuket. Most locals and tourist didn’t have a tsunami come to mind. It had rained the night before and then. The day of the tsunami was a beautiful day. It was almost 10:30 o’clock in the morning […]

Plate Tectonics and it’s Role

It’s been a few weeks since we began Science class and we’ve learned a lot of interesting things, and some of those things include, landforms that form at convergent boundaries, landforms that form at divergent boundaries, how convection currents work inside the earth, the theory of plate tectonics, and don’t even get me started on the process that adds new material to the ocean floor. And fun fact, very few people actually remember what they learn during the first few […]

Hout Bay Field Trip

The cape Granite is an intrusive igneous rock that has been exposed to the surface of the Earth, formed by solidification of magma beneath the Earth’s surface. The rock contains minerals; feldspar, quartz and biotite, and it is also coarse grained, as evident with igneous intrusive rocks. The feldspar grains are approximately 6 cm, with a white colour. Incoming waves have an approximate height and period of 0.65 m and 9 s respectively. There is a longshore drift of sand, […]

Field Observations and Data Interpretations

Data Interpretations The coastline is emergent. The beach is above ground due to tectonic uplift or a decrease in the elevation of sea level. Tides can erode the beach and take away sand. Sand can also be brought in and deposited in the berm during high tide. The longshore current moves parallel to the shore and brings sediment into and out of the beach system. Beach sand will move forward or backward depending on the direction of incoming waves. I […]

What is a Volcano?

Volcanoes are mountains that have an opening where molten lava flows down from the side. Most of these volcanoes ruin villages. Volcanoes are usually active and most people who live near one don’t know it. People mostly die from volcanoes.Where volcanoes occur is magma that rises to the surface at the edges of the plates, this means that the volcanoes are mostly spaced out around the Earth in long thin lines. A, plate edges stretch all the way around the […]

Volcano Eruptions

Volcanic eruptions can cause a lot of damage to both nearby areas and areas miles away from the eruption site. There are many different effects after an eruption that create a health hazard for both human and wildlife alike. When a volcano erupts it is very powerful and the effects of it can be felt on other continents. Volcano eruptions have even destroyed entire cities throughout history most famously Pompeii was buried by volcanic ash in 79 A.D. There are […]

Hawaii Volcanoes National Park

The towering summits and unique topographical landscape of Hawaii are a direct result of the geological processes that created grandiose volcanoes. Hawaii Volcanoes National park is home to two awe-inspiring volcanoes: Mauna Loa and Kilauea. Both members of the park are not just active, they’re are recognized some to be some of the most active in the world. Five volcanoes make up the Big Island of Hawaii: the park’s volcanoes, Mauna Loa and Kilauea, and Hualalai, Mauna Kea, and Kohala. […]

Volcanoes and their Landforms

When it came to deciding what topic to choose for this research paper, I selected volcanoes because they have always captivated me. After all, I’ve seen them my whole life in books and in movies. Lakes of fire and explosive aerial bombs tend to be fascinating. But the thing was, I didn’t really understand how it all worked. I wanted to find out more. Specifically, I wanted to know how volcanoes are created. What are the processes at work that […]

Volcano Stem Project

The composite volcano sometimes known as stratovolcanoes are steep symmetrical cones that make up some of the most famous mountains for example Mount St. Helens, Mount Fuji and Mount Rainier. These volcanoes have formed over hundreds of thousands of years through multiple eruptions. Composite volcanoes are fed by a conduit system which taps into a reservoir of magma deep within the earth says universetoday.com. This magma can erupt out of several vents across the composite volcano’s flanks or from a […]

Volcanoes in Portland, Oregon

Located in Portland, Oregon, there lie many volcanoes. When thinking of volcanoes, Oregon doesn’t come to mind right away; however, Portland, Oregon is located along the Cascade Volcanic Arc, and is home to and around 5 volcanoes: Mount St. Helens, Mount Hood, Powell Butte Nature Park, Mount Tabor, and Rocky Butte Nature Area. Personally, I have not been to Oregon or seen any of these volcanoes first hand, but I must say Oregon is a beautiful state. If I am […]

Alaska Earthquakes Cases

There are so many things happening in our world that it’s hard to keep up with everything that going on. One thing that not many know about are the earthquakes in Alaska. Lots of people are surprised to find out that Alaska has earthquakes. Though Alaska is actually pretty used to earthquakes. Alaska records an average of 40,000 quakes every year. Earthquakes in Alaska date all the way back to 1899. The earthquakes happen because parts of Alaska sit of […]

Submarine Volcanoes

Submarine volcanoes are ruptures on the earth’s surface that are found underwater from which magma erupts. Volcanic activities on terrestrial land are widespread and accessible for study, and as a result, a lot is known about these activities. However, unlike terrestrial volcanoes, very little is known about submarine volcanic activities (Cashman & Fiske, 1991). It is because underwater volcanic activities, especially deep-sea volcanoes, are not easily detectable using hydrophones since water cannot boil as a result of the high pressure […]

Volcanic Eruptions

A volcanic eruptions are devastating events that cause mass destruction throughout our society. Volcanoes are made by lava and ash coming out of the ground and hardening. Then over time, it will create a volcano. Volcanoes kill 540 people each year(Fox News). Volcanoes can be caused by other natural disasters or pressure underneath earths surface but the destruction can be minimized by following the evacuation route. To begin with, volcano eruptions can be caused by many different things. One way […]

Alaska’s Earthquakes:Where Beauty Meets Disaster

It is no surprise to Earth Scientists that Alaska sees so many earthquakes annually. With two tectonic plates meeting under a subduction zone there is bound to be a great deal of seismic activity. There is a long history of quakes, some taking several lives, that has become a lifestyle more than an occurrence. Alaska has one of the most beautiful landscapes and one of the most dangerous natural disasters that occur all too often. With the help of many […]

The San Francisco Earthquake of 1906

It’s 5:12 AM, April 18, 1906. Extremely loud low pitched rumbling wakes many people up from their sleep. This rumbling sound was caused by the Pacific and American Tectonic plates scraping along each other at the San Andreas fault. A shock suddenly hits San Francisco, and it shakes the ground for 45 seconds. Another tremblor – 8.3 on the Richter Scale 0 hits for another 25 seconds. Chaos reigned the streets of San Francisco. Later, 4.7 square miles would be […]

A Problem of Earthquakes

Earthquakes Individuals tremble when they hear the word disaster: all words that ring a bell when “earthquake” is heard. They happen all of a sudden and cause a great many dollars in reconstruction. Therefore, the sky is the limit from there, seismic tremors are a standout amongst the most terrific events The unstoppable force of life doles out.Seismic tremors for the most part happen abruptly. There is a sudden slip in the world’s outside, which influences the earth to shake […]

Another interesting fact is that when people along long long wen the earth started to shake . I learned that they are some kind of machine that measures if a earthquake is going to kame they are used by scientist because they are the ones to alert the people from the city . I will explain about where you can’t […]

How Volcanoes are Formed?

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. The highest active volcano is Ojos del Salado. This volcano is located in South America. The effects of The volcano erupting are stuff getting burnt down and a lot of people dying because of the lava. Hawaii is one of the places to have a known volcano to […]

Yellowstone Volcano

Introduction Yellowstone National Park is located in the Rocky Mountains in Wyoming, Montana, and Idaho. It is a popular park because it is home to over 10,000 features, several mountain ridges, headwater of 3 major western river system (?, 2015). Nevertheless, to say that is a beautiful place to visit, millions of visitors are unaware that they are standing in the largest, most explosive volcanoes ever to exist. It is important for people to be informed of the geologic aspects […]

Several Types of Natural Disasters

There are some kids who grow up to their parents preparing them for earthquakes and how to survive through one, but they never ask their parents or whoever teaches them what an earthquake is. An earthquake is when the earth shakes, it could be a small tremor or a big disaster. Just because it can be called a small tremor doesn’t mean that it won’t injure someone or a building. There are plenty of small earthquakes that have took lives, […]

Tohoku Earthquake: a Horrible Disaster in Japan

Japan is an island nation with a population that has a deep connection to the environment that surrounds and nourishes them. This environment has shaped the people of Japan in many ways. Japans history as been one that has been riddled with shows of the force of nature. The March 11th 2011 Tohoku earthquake has been the worst natural disaster in Japan and arguably one of the worlds most devastating natural disasters. This disaster was not just an earthquake, but […]

Forces that Shape the Earth

Plate Tectonics The forces that shape the earth begin beneath the lithosphere. Rock in the asthenosphere is hot enough to flow slowly. Heated rock rises, moves up toward the lithosphere, cools and circulates downward. Riding above this circulation system are the tectonic plates, enormous moving pieces of the earth’s lithosphere. [pic] Plate Movement Tectonic Plates move in four different ways. When tectonic plates come into contact, changes on the earth’s surface occur. 1. Diveregnt Boundary- Plates move apart, spreading horizontally. […]
