Front

What is a Negative Feedback Loop?

Back

A process that prevents small changes from getting larger, helping to maintain stability in systems.

Front

What type of boundary is formed when two tectonic plates collide?

Back

Convergent boundary.

Front

What type of boundary occurs when two tectonic plates move apart?

Back

Divergent boundary.

Front

What is the effect of rising carbon dioxide levels on Earth's temperature and photosynthesis?

Back

As CO2 levels rise, Earth's temperature increases, leading to higher photosynthesis rates, which can reduce CO2 levels through plant absorption.

Front

Which two spheres interact when plants draw nutrients from the soil?

Back

The biosphere and the geosphere.

Front

Define the term 'Biosphere'.

Back

The global sum of all ecosystems, where life exists, including land, water, and the atmosphere.

Front

What is the role of the Geosphere in Earth Science?

Back

The geosphere includes the solid parts of the Earth, such as rocks, soil, and landforms, and plays a crucial role in supporting life.

Front

Explain what a Transform Boundary is.

Back

A boundary where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is the greenhouse effect?

Back

The warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

Define 'Hydrosphere'.

Back

The combined mass of water found on, under, and above the surface of a planet.
