6th Grade Formative: Energy/ Resources

Suppose most of the water, carbon dioxide, and methane gas were taken out of the Earth’s atmosphere. How would this MOST likely affect the Earth’s temperature?

• The greenhouse effect would be stronger, so Earth’s temperature would increase.

• The greenhouse effect would be stronger, so Earth’s temperature would decrease.

• The greenhouse effect would be weaker, so Earth’s temperature would increase.

• The greenhouse effect would be weaker, so Earth’s temperature would decrease.

Which table correctly contrasts the energy the Earth receives from the Sun with energy from the Earth’s interior?

• Energy from the Sun: Reaches Earth's surface through convection; Energy from the Earth's Interior: Reaches Earth's surface through conduction.

• Energy from the Sun: Reaches Earth's surface through conduction; Energy from the Earth's Interior: Reaches Earth's surface through convection.

• Energy from the Sun: Reaches Earth's surface through conduction; Energy from the Earth's Interior: Reaches Earth's surface through radiation.

• Energy from the Sun: Reaches Earth's surface through radiation; Energy from the Earth's Interior: Reaches Earth's surface through convection.

• number of hours the lanterns provided light

Why would a law MOST likely be enacted to prevent oil spills in the ocean?

• Oil increases the surrounding air temperature.

• Oil can burn when spilled on the surface of water.

• Oil harms marine life and damages the ecosystem.

• Oil is very profitable and is used all over the world.
