Unit 4- Geoscience Processes

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is the main cause of erosion on Earth's surface?

Back

Running water is the main cause of erosion on Earth's surface.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process where tectonic plates move apart at mid-ocean ridges, creating new oceanic crust.

Front

What typically triggers a mudslide?

Back

Mudslides typically occur after a lot of rain.

Front

What is the theory of plate tectonics?

Back

The theory of plate tectonics explains how the Earth's plates move and interact, leading to geological phenomena like earthquakes and volcanic activity.

Front

What evidence supports the theory of plate tectonics?

Back

Evidence includes the distribution of minerals and fossils, geographic features, and the way continents fit together like a puzzle.

Front

What forms at a divergent plate boundary?

Back

A mid-ocean ridge forms at a divergent plate boundary.

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 a mudslide?

Back

A mudslide is a rapid flow of mud down a slope, often triggered by heavy rainfall.

Front

What are the three main types of plate boundaries?

Back

The three main types of plate boundaries are divergent, convergent, and transform boundaries.
