ESSRT 2024 PAGES 11 & 12 review

Front

What is the composition of the Earth's inner core?

Back

The inner core is solid and primarily composed of iron and nickel.

Front

What is the difference between oceanic crust and continental crust?

Back

Oceanic crust is thinner and denser, while continental crust is thicker and less dense.

Front

What latitude line was North America closest to 359 million years ago?

Back

North America was closest to the Equator.

Front

What type of plate boundary is associated with subduction zones?

Back

Subduction zones are found at convergent plate boundaries.

Front

What geological process occurs at subduction zones?

Back

At subduction zones, one tectonic plate moves under another and sinks into the mantle.

Front

What are convection currents?

Back

Convection currents are the movement of fluid caused by differences in temperature and density.

Front

What is the role of the mantle in plate tectonics?

Back

The mantle's convection currents drive the movement of tectonic plates.

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.

Front

What happens at divergent plate boundaries?

Back

At divergent plate boundaries, tectonic plates move apart, leading to the formation of new oceanic crust.

Front

What is the definition of a tectonic plate?

Back

A tectonic plate is a large slab of solid rock that makes up the Earth's lithosphere.
