What is the principle of superposition in geology?

Back

The principle of superposition states that in sedimentary rock layers, younger layers are found on top of older layers.

Front

What is a landslide?

Back

A landslide is a geological event where a large amount of rock and soil moves down a slope due to gravity, often triggered by rain or earthquakes.

Front

Where do volcanoes most likely form?

Back

Volcanoes most likely form where tectonic plates meet other plates, especially along plate boundaries.

Front

What is a plateau?

Back

A plateau is a flat, elevated area of land that rises sharply above the surrounding area.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological events like earthquakes and volcanoes.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic plate movements.

Front

What is sedimentary rock?

Back

Sedimentary rock is formed by the accumulation and compaction of mineral and organic particles, often in layers.

Front

What causes a tsunami?

Back

A tsunami is caused by underwater earthquakes, volcanic eruptions, or landslides that displace a large volume of water.

Front

What is a foothill?

Back

A foothill is a low hill at the base of a mountain range.
