Earth Science Flashcard

Front

What keeps the innermost part of Earth in a solid state?

Back

Extremely high pressure.

Front

How do tectonic activities contribute to long-term climate change?

Back

By releasing greenhouse gases from volcanic eruptions.

Front

What is the role of tectonic plates in glaciations?

Back

They influence the position of continents, affecting global climate patterns.

Front

Where is the youngest rock located on the floor of the Atlantic Ocean?

Back

Close to the top of the mountains on both sides of the Mid-Atlantic Ridge.

Front

How does radioactive decay affect motion within Earth?

Back

The density of molten rock decreases as it is heated, resulting in the rock being pushed above by material with a greater density.

Front

What is the Mid-Atlantic Ridge?

Back

A divergent fault on the ocean floor that forms a mountain chain running from north to south.

Front

What is the significance of greenhouse gases in climate change?

Back

They trap heat in the atmosphere, leading to global warming.

Front

How do volcanic eruptions influence the atmosphere?

Back

They release ash and gases, including greenhouse gases, which can affect climate.

Front

What is the relationship between tectonic plate movement and earthquakes?

Back

The movement of tectonic plates can cause stress to build up, leading to earthquakes when released.

Front

What is the process of subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.
