Which of the following is the rigid solid layer of the upper mantle that is connected to the cross?

Which of the following is the rigid solid layer of the upper mantle that is connected to the cross?

lithosphere

What is the connection of lithosphere and asthenosphere?

The lithosphere is the brittle crust and uppermost mantle. The asthenosphere is a solid but it can flow, like toothpaste. The lithosphere rests on the asthenosphere.

What do you call the rigid outer part of the Earth?

The lithosphere is the rocky outer part of the Earth. The lithosphere is the coolest and most rigid part of the Earth.

Which part of the mantle is still a solid but flows like a thick heavy liquid?

asthenosphere

Which of the following best describes the asthenosphere?

Asthenosphere is a partially melted layer of earth and is a part of upper mantle. It is composed of partial melt and rocks. the lithosphere moves over the asthenosphere due to its flexible property. asthenosphere extends from the base of lithosphere up to 660 km below the surface.

What layers are in the asthenosphere?

The asthenosphere acts as the lubricating layer below the lithosphere that allows the lithosphere to move over the Earth’s surface. The mantle is the layer of the earth that lies below the crust and is by far the largest layer making up 84% of Earth’s volume.

What elements is the asthenosphere made of?

The asthenosphere is also known as the “low velocity” zone of the mantle because seismic waves slow down as they pass through it. This property tells us that the asthenosphere is composed of partially molten rock slushlike material consisting of solid particles with liquid occupying spaces in between.

What is difference between crust and mantle?

Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma.

What are the two types of plates?

There are two main types of tectonic plates: oceanic and continental.

What are the 2 types of crustal plates?

The two types of tectonic plates are continental and oceanic tectonic plates.

How can tectonic plates move?

Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

What is the four type of boundary?

Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another. Transform boundaries — where crust is neither produced nor destroyed as the plates slide horizontally past each other.
