Plate Tectonics

Front

What are hot spots in relation to plate tectonics?

Back

Hot spots are volcanically active areas that are not located near tectonic plate boundaries.

Front

What is the primary theory that explains the movement of tectonic plates?

Back

Plate Tectonics is the theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates.

Front

What causes tectonic plates to move?

Back

Tectonic plates move due to convection currents in the mantle, which involve the circular pattern of heating, rising, cooling, and sinking of magma.

Front

How many types of crust are there?

Back

There are two main types of crust: continental crust and oceanic crust.

Front

What is an index fossil?

Back

An index fossil is a fossil that is used to help date strata due to its existence during a specific time period.

Front

What geological features are commonly associated with subduction zones?

Back

Subduction zones are commonly associated with earthquakes, volcanic activity, and the formation of mountain ranges.

Front

What is the Mid-Atlantic Ridge?

Back

The Mid-Atlantic Ridge is a divergent boundary between tectonic plates where new oceanic crust is formed.

Front

What is the significance of earthquakes in plate tectonics?

Back

Earthquakes are significant as they are often caused by the movement of tectonic plates and can indicate the boundaries and interactions of these plates.

Front

What role do convection currents play in plate tectonics?

Back

Convection currents in the mantle drive the movement of tectonic plates by transferring heat from the Earth's interior to the surface.

Front

What is the difference between continental crust and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.
