Question 1

Which of the following is a defining characteristic of freshwater ecosystems?

They include ponds, most lakes, streams, and rivers.

Sunlight cannot reach their deepest areas.

They always contain water all year round.

They are characterized by a high concentration of natural salts.

Question 2

Most of Earth's surface water is found in lakes, rivers, seas, and oceans, where it exists primarily in a liquid state.

True

False

Question 3

How does the hydrosphere directly support the biosphere?

It regulates Earth's magnetic field.

It provides the water essential for all living processes.

It forms the solid crust of the planet.

It generates the oxygen found in the atmosphere.

Question 4

What is respiration in the context of Earth system interactions?

It is a process performed by plants that involves the atmosphere and biosphere.

It describes the movement of molten rock within the Earth.

It exclusively involves the formation of water bodies like lakes.

It is a process that primarily forms new landforms.

Question 5

Rivers are freshwater ecosystems where plants and animals thrive in always-moving water.

False
