Earth Science Module 1 - Pre-Assessment

Which is NOT one of the reasons why the hydrosphere is important?

• It sustains various life forms

• It helps in regulating the atmosphere

• It plays an important role in ecosystems

• It plays a major role in the movement of tectonic plates.

Which of the following is the reason for the importance of Earth’s subsystems?

• The subsystem influence Earth’s encounter with space objects

• The subsystems solely determine the survival of different organisms

• The subsystems contribute scarcely in flow of matter and energy

• The subsystems influence the climate, geological processes, and life on Earth

Why is the ozone layer important in sustaining life on earth?

• It is where Earth satellites orbit and auroras show.

• It influences hydro-meteorological phenomenon such as storms.

• It shields the Earth the Sun's ultraviolet radiation and keeps the planet warm.

• It is where celestial objects get burned and disintegrated upon entering Earth.

Which subsystem helps regulate the temperature of the Earth so we do not experience too much hotness or coldness?

• Biosphere

• Lithosphere

• Atmosphere

• Hydrosphere

Earth system science studies the roles and relationships of the 4 subsystems. Which of them is considered as the integral subsystem?

• The atmosphere because climatic changes and weather are important

• The biosphere since living organisms is the heart of all interactions

• The geosphere because the movement of crust changes history and era

• The hydrosphere since it provides water, a key molecule for phenomena to occur and for life to prosper
