PRE FINALS PRACTICE TEST

Front

What is the role of the biosphere in maintaining the balance of gases in the atmosphere?

Back

Plants in the biosphere take in carbon dioxide and release oxygen, helping to regulate atmospheric gases.

Front

Which Earth subsystem benefits the most from the Earth's core generating a strong magnetic field?

Back

Atmosphere – it protects living organisms from harmful solar radiation.

Front

Why are tectonic plates able to move on the Earth’s surface?

Back

The lithosphere floats on the semi-fluid asthenosphere beneath it, allowing plate movement.

Front

What effect does increased volcanic activity in the geosphere have on the atmosphere?

Back

Volcanic eruptions release gases like carbon dioxide and sulfur dioxide, contributing to climate change.

Front

Why is the Earth's inner core solid despite extreme temperatures?

Back

The intense pressure at the core's depth prevents the iron and nickel from melting.

Front

What is the biosphere?

Back

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

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases surrounding the Earth, essential for life and climate regulation.

Front

What is the geosphere?

Back

The geosphere is the solid part of the Earth, including rocks, soil, and the Earth's interior.

Front

What is the hydrosphere?

Back

The hydrosphere encompasses all water on Earth, including oceans, rivers, lakes, and groundwater.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.
