Earth's atmosphere

Question 1

Which statement best describes how the geosphere and hydrosphere interact when a river flows over land?

Accepted Answer

The river erodes the soil and carries sediment into the ocean.

Answer

The river provides oxygen for fish living in the water.

Answer

The river’s water evaporates and forms clouds in the sky.

Answer

The river’s flow is powered by the Earth’s magnetic field.

Question 2

A science museum has four separate exhibits: one on rocks and mountains, one on rivers, lakes and oceans, one on the air we breathe, and one on plants and animals. Which list correctly names the four Earth systems represented by these exhibits?

Accepted Answer

Geosphere, Hydrosphere, Atmosphere, Biosphere

Answer

Lithosphere, Hydrosphere, Atmosphere, Biosphere

Answer

Geosphere, Hydrosphere, Weather, Biosphere

Answer

Geosphere, Aquifer, Atmosphere, Biosphere

Question 3

A dense forest on a hill is cleared and planted with wheat. Select the answer that most accurately traces the ripple effects on all four Earth systems after this change.

Accepted Answer

Removing the trees exposes the soil, so erosion adds sediment to nearby streams (geosphere → hydrosphere); fewer trees mean less photosynthesis, lowering oxygen and raising CO₂ in the air (biosphere → atmosphere); the wheat field becomes the new dominant living community (biosphere).

Answer

Only the living things change because the forest becomes a wheat field; the land, water, and air stay the same.

Answer

The wheat plants enrich the soil, so the water in streams becomes clearer and the air gets less CO₂ because the plants take it up.

Answer

Clearing the forest makes the ground hotter, warming the air, which then causes the nearby river to freeze.
