Geosphere Test

Front

What is the lithosphere?

Back

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

Front

What layer do tectonic plates glide over?

Back

Tectonic plates glide over the asthenosphere, which is a semi-fluid layer beneath the lithosphere.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces due to environmental factors like water, wind, ice, and gravity.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind, water, or ice.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down materials in place, while erosion involves the movement of those materials to a different location.

Front

Which is more dense: continental crust or oceanic crust?

Back

Oceanic crust is more dense than continental crust.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a tectonically active area around the edges of the Pacific Plate, known for its numerous volcanoes and earthquakes.

Front

What causes volcanic activity in the Ring of Fire?

Back

Volcanic activity in the Ring of Fire is primarily caused by the movement of tectonic plates and subduction zones.

Front

What is a tectonic plate?

Back

A tectonic plate is a massive slab of solid rock that makes up the Earth's lithosphere and moves over the semi-fluid asthenosphere.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often causing volcanic activity.
