What Layer Is Soft Bendable? ASTHENOSPHERE: Soft – can bend like plastic, layer in the upper portion of the mantle. It is located right below the Lithosphere. Which layer of the Earth is bendable? The outer core is the only liquid layer of the earth; a sea of mostly iron and nickel. Lithosphere: made up
How Deep Is The East Pacific Rise? It rises from approximately 6,000 to 9,000 feet (1,800 to 2,700 metres) above the surrounding seafloor and is extensively fractured by faults mostly occurring at intervals of roughly 200 miles (320 km). Where does the East Pacific Rise start and end? It runs south from the Gulf of
Is It Possible To Dig Through The Earth? We can barely dig a tunnel just a few kilometers into the reasonable outer crust of the Earth. Forget digging down through the hotter part of the crust, into the mantle, where rock squishes and oozes around like jello. How far can you dig into the Earth?
Which Term Is Described As A Flat Expanse Of The Ocean Floor? Which term is described as a flat expanse of ocean floor? Abyssal Plains. Which feature of the ocean floor is the continental shelf? The continental shelf is an area of relatively shallow water, usually less than a few hundred feet deep, that surrounds
Which Layer Is Usually The Oldest? The oldest layers are on the bottom, and the youngest layers are on the top. Because sediments sometimes include once-living organisms, sedimentary rock often contains a lot of fossils. Is Bedrock the oldest layer? Bedrock along the northeast coast of Hudson Bay, Canada, has the oldest rock on Earth.
What Is The Oceanic Crust Made Of? Oceanic crust, extending 5-10 kilometers (3-6 kilometers) beneath the ocean floor, is mostly composed of different types of basalts. Geologists often refer to the rocks of the oceanic crust as “sima.” Sima stands for silicate and magnesium, the most abundant minerals in oceanic crust. (Basalts are a sima
Where Is The Oldest Oceanic Crust In The Oceans? The oldest patch of undisturbed oceanic crust on Earth may lie deep beneath the eastern Mediterranean Sea – and at about 340 million years old, it beats the previous record by more than 100 million years. Which ocean is the oldest ocean? The Pacific is the
Which Type Of Crust Is The Thickest The Thinnest? Out of them, the mantle is the thickest layer, while the crust is the thinnest layer. The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the mantle is
Why Is It Important To Learn About The Layers Of The Earth? The layers of Earth provide geologists and geophysicists clues to how Earth formed, the layers that make up other planetary bodies, the source of Earth’s resources, and much more. What do we learn from studying layers of the Earth’s surface? By studying rocks
Why Does Melting Occur Along Mid-ocean Ridges? As mantle ascends beneath the mid-ocean ridge, less and less rock lies above it, so large pressure changes occur, which leads to melting. The melt is less dense than the solid, and rises to the surface to form the oceanic crust. What type of magma is mafic? Mafic
