Rocks are heated underneath the crust then pushed out through a volcano or the oceanic plate. The rock substance that becomes the crust will deposit back underneath the crust. All of the process can be credited to the dynamic nature of Earth.
- Crust - cool, lightweight, brittle, which floats on top of mantle. It is the outer layer of earth. Tectonic processes reshape continents and also cause earthquakes - Tectonic plates- plates caused by convection currents in the mantle that causes earthquakes. - Ocean basins form where continents crack and pull apart. - Magma – is molten rock
The Connecticut river valley was also formed from many rifts and faults that had developed. A rift valley is a region of lowland that forms where tectonic plates move apart, which is how the river valley was formed. On the other hand, the plate tectonics also formed the Appalachian mountains. The Appalachian mountains were formed by convergent boundaries, which is when two plates collide. The
Its outer boundary is around 2,890km beneath the earth’s surface. 3. The Mantle: The mantle is the layer between the crust and the outer core, which is the broadest section of the Earth. It has a wideness of roughly 2,900.
On a sunny day, the land absorbs heat from the sun more quickly than the water does. The air over the land becomes warmer as some of this absorbed heat is radiated back into the air. The warmer air begins to rise, and the cooler air over the water moves in to take its place. At nighttime when the sun goes down, the land cools off quickly, but the water does not. The water radiates some of its stored heat into the air, and this warmed air begins to rise.
When the layers of the Earth move it causes the tectonic plates (aka: plate tectonics) to move which causes the Alaskan Way Viaduct to collapse. The layers of the Earth are the inner core, outer core, mesosphere, asthenosphere, upper rigid mantle, oceanic crust, and the continental crust. The Density Column lab showed how things can have different densities like the layers of the Earth. It also showed how things that are most dense stay more towards the bottom and least dense stuff stays more towards the top.
The Canadian Shield is arguably the best land form region. Tectonic forces and glaciation have combined to shape the Canadian shield, making it different from other Canadian landform regions, directly affecting economic activity. Firstly, Tectonic Activity created the base of the Canadian Shield is 2.5 billion years old craton made of igneous rock. Tectonic activity directly affects the Canadian Shield to this day, because many economic activities take place on the rock.
The two plates that moved were the North American tectonic plate and the Pacific tectonic plate. The plates moved about 15 feet, this is huge because the average movement of tectonic plates during an earthquake is only 2 inches. The earthquake only lasted a minute but it quickly destroyed the city. The earthquake
Natural disasters leave people scared and lonely like fish stranded without water to survive. Rogue waves and tsunamis are both huge, deleterious, and life threatening natural disasters. The two storms are practically unpredictable and cause great destruction wherever they strike. Although rogue waves and tsunamis seem alike on the surface, when diving deep into the information about them, one can see just how different they are.
How do earthquakes form? Earth quakes form when two earth blocks slide past each other. When they slip past each other it is called a fault. Earth quakes
A brief description of geology is the study of Earth's physical structure. The Apollo missions allowed scientists to understand the planet further. The missions gave access to the formation of materials on other planets giving them an idea of how our planet was formed. Professor Smith, a geologist from the University of Chicago proclaims,” In general,
Plate tectonics is a theory that Earth’s crust is composed of nearly a dozen plates, which have shifted around the surface of the Earth over time. This theory provides a reasonable explanation for how mountains formed, and why there are earthquakes and volcanoes. Additionally, this
These two plates push and shove each other causing small tremors throughout which can cause landslides,volcanic eruptions and once in a couple years, quakes with devastating results. The strongest earthquake recorded occurred in 1991 with a measure of 7.6 on the Richter scale. This earthquake left 4 dead and buildings as well as bridges and road were completely destroyed. If another Earthquake occurs, the coastal cities would be the most affected ones as they are closer to the plates.
I believe we should not move to Los Angeles, California. I think we shouldn’t relocate because of the dangers of California. First of all, California resides inside the eerie Pacific Ring of Fire. The Pacific Ring of Fire is an area within the basin of the Pacific Ocean where the most amount of earthquakes and volcanic eruptions occur, creepy, isn’t it? Additionally, California faces the highest risk of earthquakes.
Continental drift makes the Earth’s climate change in many ways, ocean currents being one of them. When a continent is close to a large body of water, the water averages the temperature and administers more moisture. The ocean currents are responsible for moving water around the Earth. If land masses move closer to the North Pole, the
