Unit 1 Lesson 1 - Energy in Earth's Systems

Which is NOT a reason to build a physical model of the Earth’s biosphere?

• To monitor how the biosphere changes over time.

• To find out what the biosphere is like on other planets.

• To test an artificial environment that would allow people to live on Mars.

• To observe the interaction of the geosphere, hydrosphere, atmosphere, and biosphere in a controlled environment.

What is NOT included in the atmosphere?

• Oxygen

• Water vapor
• Solid objects (e.g., rocks)
• Carbon dioxide

Deep currents are __________.

• Cold because cold water is denser than warm water so it sinks.

• Not cold. Surface currents are cold.

• Cold because the water becomes cold after it sinks due to conduction.

• Cold because cold water is less dense so it sinks.
