What is an alternative energy source?

Back

An energy source that is not based on fossil fuels and is more sustainable, such as solar, wind, or hydro energy.

What are the two possible outcomes of a divergent plate boundary?

Back

Rift valley and mid-ocean ridge.

Front

What type of plate boundary results in the formation of mountains like the Himalayas?

Back

Convergent plate boundary.

Front

What happens to Earth when the ozone layer is damaged?

Back

More UV radiation reaches the Earth's surface.

Front

What is an index fossil?

Back

A fossil of an organism that existed for a long time geologically and distributed over a wide area.

Front

What is the main purpose of using alternative energy sources?

Back

To reduce reliance on fossil fuels and minimize environmental impact.

Front

What is a rift valley?

Back

A lowland region formed by the divergence of tectonic plates.

Front

What is a mid-ocean ridge?

Back

An underwater mountain range formed by plate tectonics at divergent boundaries.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often forming mountains or causing subduction.

Front

What is the impact of increased UV radiation on human health?

Back

It can lead to higher rates of skin cancer and other health issues.
