Plate Tectonics TEST Review

Front

What is the Stiffer Mantle?

Back

The Stiffer Mantle is a layer of the Earth's interior located below the asthenosphere and above the outer core, characterized by high pressure and temperature, where the pressure can reach about 1 million atmospheres.

Front

What is the temperature at the boundary of the Stiffer Mantle and Outer Core?

Back

The temperature at the boundary of the Stiffer Mantle and Outer Core is approximately 5000 °C.

Front

What type of boundary do mid-ocean ridges represent?

Back

Mid-ocean ridges represent divergent boundaries, where tectonic plates move apart from each other.

Front

What is the difference in arrival times between P-waves and S-waves during an earthquake?

Back

The difference in arrival times between P-waves and S-waves can be used to determine the distance to the earthquake epicenter; for example, a difference of 6 min. 10 sec. indicates a specific distance.

Front

What are P-waves?

Back

P-waves, or primary waves, are seismic waves that compress and expand the material they move through, and they are the fastest type of seismic wave.

Front

What are S-waves?

Back

S-waves, or secondary waves, are seismic waves that move the ground up and down or side to side, and they are slower than P-waves.

Front

What is the role of the asthenosphere in plate tectonics?

Back

The asthenosphere is a semi-fluid layer of the upper mantle that allows tectonic plates to move over it, facilitating plate tectonics.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to subduction or mountain building.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, causing earthquakes.

Front

What is the significance of the Earth's lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle, and it is divided into tectonic plates.
