Front

What is the Theory of Plate Tectonics?

Back

The Theory of Plate Tectonics explains how the Earth's outer shell, or lithosphere, is divided into several plates that glide over the semi-fluid asthenosphere beneath. This movement causes geological events like earthquakes, volcanic eruptions, and the formation of mountains.

Front

What are the three main layers of the Earth?

Back

The three main layers of the Earth are the core (innermost layer), the mantle (middle layer), and the crust (outermost layer).

Front

What is the crust of the Earth?

Back

The crust is the thin and solid outermost layer of the Earth where tectonic plates move.

Front

What happens when tectonic plates move apart?

Back

When tectonic plates move apart, a rift valley can form, which is a low area between two plates.

Front

What is a rift valley?

Back

A rift valley is a lowland region that forms where tectonic plates move away from each other, often leading to volcanic activity.

Front

What geological feature is formed by the collision of tectonic plates?

Back

The collision of tectonic plates can lead to the formation of mountain ranges, such as the Himalayas.

Front

What is a tsunami?

Back

A tsunami is a series of large ocean waves caused by underwater earthquakes or volcanic eruptions.

Front

What natural disaster can occur as a result of an underwater earthquake?

Back

A tsunami can be triggered by an underwater earthquake.

Front

What is the relationship between earthquakes and tectonic plates?

Back

Earthquakes occur when stress builds up along fault lines between tectonic plates, leading to sudden releases of energy.

Front

What is the mantle?

Back

The mantle is the thick layer of the Earth located between the crust and the core, composed of semi-solid rock that flows slowly.
