BJHS Science 8 - Plate Tectonics Retest

Front

What is convection current?

Back

Convection current is the movement of fluid (liquid or gas) caused by the uneven heating of the fluid, which creates areas of different temperatures and densities.

Front

How does heat transfer from the Earth's core to the surface?

Back

Heat from the Earth's core reaches the surface primarily through convection currents in the mantle.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath the other, leading to geological features like mountains or volcanic activity.

Front

What landform is created by constructive volcanic eruptions?

Back

Constructive volcanic eruptions can lead to the formation of new islands.

Front

What is the asthenosphere?

Back

The asthenosphere is a layer of the Earth's mantle that is made of dense molten rock and is capable of flowing, allowing tectonic plates to move.

Front

What geological forces create mountain ranges?

Back

Mountain ranges are often formed by converging tectonic plates that push the Earth's crust upwards.

Front

What is the difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact, while convection is the transfer of heat through the movement of fluids.

Front

What is the role of tectonic plates in earthquakes?

Back

Tectonic plates can cause earthquakes when they move past each other, collide, or pull apart, releasing energy in the form of seismic waves.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another, often leading to volcanic activity and the formation of deep ocean trenches.
