What part of the earths mantle that flows and moves the plates of the earth?

Mantle plumes are in the mantle, BELOW the Earth's crust. The circulation of heat from the lower mantle to the upper mantle can cause "hot spots" in the overlying crust, heating the magma in the areas.

What is the earth's layer of solid rock that flows under pressure?
The solid layer of the earth that can still flow is called the asthenosphere. This layer is located in the mantle of the earth the layer below the upper crust and lithosphere, home of the tectonic plates.
Does Niger ever suffer from earthquakes?
Yes, everywhere has or will expirience earthquakes. The world is made up of techtonic plates, large pieces of Earth that sit on top of the toothpaste-like mantle. As the mantle flows, the plates move. When the plates collide, pressure builds up. When all the pressure is released, there is an earthquake. Niger is not on a plate boundary, but when two plates push in opposite directions on one plate (sandwiching it) pressure builds up on the plate in the middle. Eventually, the plate could "crack". It splits similarly to when a cracker is being pushed on on two sides, then cracks in half. Niger would be a possibility for this to happen. So, yes, Niger can have Earthquakes.
How is water heated for geothermal power plants?
The water is hot because it comes from the earths mantle. If the hot springs is in a volcanic zone like Yellowstone national park, water may be heated by the magma in the volcano near by.
What term describes magma that flows out onto earths surface?
Lava ;D
Heat from the earths center flows toward the suface because why?
Heat from the Earth rises to the surface because heat rises. Heat rises because it is energy and the atoms are looking for more space to move freely in.
Can the mantle layer of the earth soften?
Not as such, but the Mantle "flows".
How has the study of earthquakes helped us understand the inner layer of the earth?
Earthquakes are caused by a shift in two different plates beneath the earths surface. The shift is usually caused by convectional magma flows underneath the earths crust. This is because the plates are purely floating slabs of rock on the magma beneath it. The layer beneath the crust is called the mantle.
What is the opening on earths surface where magma from the mantle rises and flows out?
Valcano
Why do Scientists believe that forces in the Earth's mantle move the Earth's crustle plates What do the arrows in the diagram represent?
The arrows represent convection and how magma flows through the mantle. When a divergent boundary is formed, the land sinks into the mantle and goes through the convection system.
What is below the lithosphere and how does this help to explain the theory of plate tectonics?
The lithosphere of the Earth is composed of the crust and the upper part of the upper mantle, and is broken up into plates. Below the lithosphere is the asthenosphere, which is the lower part of the upper mantle and the entire lower mantle. The asthenosphere is a plastic-like substance that flows due to convection. As this substance flows, it causes the plates above it to move around. Plate tectonics is the theory that the lithosphere is divided into plates that are constantly in motion.
What is the area of the earth That flows Like a thick liquid?
The mantle
What is the earth's layer of solid rock that flows under pressure?
The solid layer of the earth that can still flow is called the asthenosphere. This layer is located in the mantle of the earth the layer below the upper crust and lithosphere, home of the tectonic plates.
How does heat flow through Earth's mantle?
It flows by getting so hot.
What is the mantle composts of?
The Earth's mantle is mostly composed of silicate rocks that are rich in iron and magnesium. Although it's mostly solid, it's hot enough that it can flow over long timescales. The upper mantle flows more easily than the lower mantle because of the increasing temperature and pressures as you descend into the Earth. The Earth's tectonic plates float on top of the mantle. In some places, the plates are sliding under one another, returning rock back to the interior of the Earth. In other places, the plates are spreading apart, and fresh volcanic material is welling up to fill the cracks. Inside the mantle, convection is slowly taking place - like in a lava lamp. Hotter material, heated by the core of the Earth rise slowly to the surface of the mantle. Material cools near the crust and then sinks back down to the core, to repeat the process all over again. It's believed that this convection helps drive the motions of Earth's tectonic plates.
How is heat is transferred from the core to the surface?
In the main by slow convection flows in the Earth's mantle.
What is the semi rigid layer of solid rock that flows very slowly called?
The rock layer beneath the Earth's surface that slowly flows is the mantle. (Given enough time, all rocks, even the most solid, will flow through molecular motion.)The mantle is a slowly convecting layer of rock which flows in order to transfer heat from the core to the Earth's surface. It is this convection that drives the movements of the continents and can cause volcanic mountains to form.The athenosphere is the highly viscous, mechanically-weak and ductilely-deforming upper mantle of the Earth. It is the zone upon which the great rigid and brittle lithospheric plates of the Earth's crust move about. However, the whole mantle is flowing, albeit very slowly.
What gives rise to the Earths magnetic field?
Current flows inside he Earth.
