What would be the best title for this graphic?

• The Three Laws of Thermodynamics

• Potential and Kinetic Energy

• The Process of Photosynthesis

• The Earth's Energy Budget

• 75

• 90

• 100

• 120

According to this graphic, the majority of the energy from the sun is—

• Absorbed by the land and oceans

• Reflected by the atmosphere

• Reflected by the clouds

• Absorbed by atmosphere and clouds

The main cause of the Greenhouse Effect is excess—

• Solar flares

• Carbon dioxide

• Oxygen

• Radio waves

Which of the following statements are true about energy on Earth? Choose two (2) correct answers.

• The Earth receives the sun’s energy after it is reflected off the moon.

• Earth receives only a very small portion of the sun’s energy.

• The sun’s energy powers many processes on Earth’s surface.

• Earth’s surface is heated equally.

• Every night, the Earth loses the energy it gained from the sun during the day.

A flowchart showing a sequence: [Blank] → Molecules move faster and farther apart → [Blank] → [Blank]. Below are the options: Density is reduced, Molecules rise, Water or air is heated. Students are to place each option in the correct box to show cause and effect.

• Water or air is heated → Molecules move faster and farther apart → Density is reduced → Molecules rise

• Molecules rise → Molecules move faster and farther apart → Water or air is heated → Density is reduced

• Density is reduced → Molecules move faster and farther apart → Molecules rise → Water or air is heated

• Water or air is heated → Molecules move faster and farther apart → Molecules rise → Density is reduced

Cooler air moves under warm air because the cooler air—

• Moves faster

• Is denser

• Contains a higher percentage of oxygen

• Has more potential energy

This best title for this graphic would be—

• Humans’ Dependence on Energy

• Cause and Effects of Increased Greenhouse Gases

• The Role of Excess Carbon Dioxide in the Distribution of Energy

• How Convection Currents Distribute Thermal Energy

Which of the following is true about how energy moves through Earth's atmosphere? (Choose 3 that apply)

• Convection brings energy from the Earth's surface to space

• Radiation carries energy from the Sun to Earth

• Convection transfers heat through the movement of air and water

• Radiation moves energy only through the Earth's surface

• Conduction moves the heat through solid ground

Why do businesses in modern industrialized societies often rely on fossil fuels as their major source of energy?

• Fossil fuels are healthier for people and the environment than renewable energy sources.

• Fossil fuels are more reliable and can provide energy at any time, regardless of weather conditions.

• Fossil fuels are unlimited and will never run out, making them the safest option for long-term use.

• Fossil fuels are cheaper to produce and have no environmental impact compared to renewable energy.
