Making North America: Origins

Erebus Volcano Observatory. Erebus is home to a permanent lava lake, or a large amount of molten lava contained in a crater. Only three volcanoes in the world have permanent lava lakes, making Mt. Erebus an important research site for scientists looking to better understand the internal plumbing system of volcanoes. However, its location permits only a six-week field season and its high altitude meters is physically challenging.

Erebus lava lake in Erebus is also notable for its persistent low-level eruptive activity with almost daily eruptions. While the volcano has had some history of violent activity, most eruptions are passive lava flows similar to the volcanoes of Hawaii. Seismic activity earthquakes is most often associated with tectonic plate boundaries. As plates slowly move, their jagged edges stick and suddenly slip, causing an earthquake.

The Gakkel Ridge underneath the Arctic Ocean experiences small earthquakes that accompany the volcanic activity found in the area. Antarctica, which lies in the center of a tectonic plate, does not experience many earthquakes. However, seismic activity is associated with eruptions of Mt. Use these resources to learn more about erosion, volcanoes, earthquakes, and plate tectonics and how these agents of change affect the polar regions.

Great article. As an earth scientist I can endorse the fact that all of the content of this website is of a high standard and factually correct although it does not cover the entire field of physical geology. As far as the processes changing the face of the earth go there is another force that can effect a drastic change to the surface of the earth i. This information is incredible. Your email address will not be published. The Forces that Change the Face of Earth Despite our tendency to consider Earth as static, it is actually a dynamic and ever-changing planet.

Meltwater streams of many glaciers are grayish in color due to high amounts of rock flour. A U shaped Valley in Alaska. Glacial moraine in Kyrgyzstan. A fjord in Norway. Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes. Lithospheric plates on the scales of continents and oceans constantly move at rates of centimeters per year in response to movements in the mantle.

Major geological events, such as earthquakes, volcanic eruptions, and mountain building, result from these plate motions. Land forms are the result of a combination of constructive and destructive forces.

Constructive forces include crustal deformation, volcanic eruption, and deposition of sediment, while destructive forces include weathering and erosion. Fossils provide important evidence of how life and environmental conditions have changed.

K-4 Science in Personal and Social Perspectives: Changes in Environments Changes in environments can be natural or influenced by humans. Some changes are good, some are bad, and some are neither good nor bad. Some environmental changes occur slowly, and others occur rapidly.

Shield Volcano : A shield volcano has low levels of dissolved gas and silica in its magma. Its eruptions are effusive, and the very fluid lava moves quickly away from the vent, forming a gently sloping volcano. Mauna Loa in Hawaii is an example.

From Mountains to Trenches

The Earth's surface is constantly changing through forces in nature. The daily processes of precipitation, wind and land movement result in changes to landforms over a long period of time.

http://leondumoulin.nl/language/art/7652-minimally-invasive-cancer.php Driving forces include erosion, volcanoes and earthquakes. People also contribute to changes in the appearance of land. Erosion breaks down land and continents into smaller forms. Wind and water movement are common types of erosion. A boulder turns into sand after years of being hit by waves and particles. A mountain eventually becomes a hill when rain breaks it apart. Ocean waves and rivers push into the sides of cliffs, shaping the land. Erosion can also create new land. As rock and other sediment are carried away by the forces of erosion, they eventually settle elsewhere.

New wetlands form at the mouths of rivers through this process. Lava ejects onto the surface of the Earth through a volcano, which is a crack in the opening of the planet's crust.

Lava pushes land up and hardens when it comes out of the Earth, and the resulting mountains are also called volcanoes.
