Fall Final Review Restless Earth

Front

What are convection currents?

Back

Convection currents are the movement of fluid (liquid or gas) caused by differences in temperature and density, which results in the transfer of heat. In Earth's interior, these currents help redistribute heat from the core to the surface.

Front

What geological features are formed at divergent plate boundaries?

Back

Mid-Ocean Ridges and Rift Valleys are formed at divergent plate boundaries where tectonic plates move apart, allowing magma to rise and create new oceanic crust.

Front

What process is responsible for shaping landscapes like the Grand Canyon?

Back

Weathering and erosion from water are the primary processes that shape landscapes like the Grand Canyon, as they break down rocks and transport sediment.

Front

Define weathering in geological terms.

Back

Weathering is the process of breaking down rocks into smaller particles or sediment through physical, chemical, or biological means.

Front

What type of plate boundary is associated with the formation of new oceanic crust?

Back

Divergent plate boundaries are associated with the formation of new oceanic crust as tectonic plates pull apart.

Front

What is the difference between erosion and deposition?

Back

Erosion is the process of transporting sediment away from its original location, while deposition is the process of laying down or settling sediment in a new location.

Front

What role does radioactive decay play in Earth's interior?

Back

Radioactive decay contributes to the heat within Earth's interior, influencing convection currents and geological activity.

Front

What are the main types of plate boundaries?

Back

The main types of plate boundaries are divergent, convergent, and transform boundaries, each associated with different geological features and processes.

Front

How do mountains form at convergent plate boundaries?

Back

Mountains form at convergent plate boundaries when two tectonic plates collide, causing the crust to fold and uplift.

Front

What is the significance of mid-ocean ridges?

Back

Mid-ocean ridges are significant as they are the sites of new oceanic crust formation and are associated with volcanic activity and earthquakes.
