Energy in Earth's Atmosphere

What is the atmosphere?

• A layer of gases surrounding the Earth that provides oxygen and protects from solar radiation.

• A solid layer of minerals that forms the Earth's crust.

• A collection of water vapor that creates clouds and precipitation.

• A vacuum that exists in space beyond the Earth's surface.

What is the difference between weather and climate?

• Weather refers to long-term average conditions, while climate is short-term atmospheric conditions.

• Weather is the average temperature over a year, while climate is the daily temperature.

• Weather refers to short-term atmospheric conditions, while climate is the long-term average of weather patterns in a specific area.

• Weather is only about precipitation, while climate includes temperature and humidity.

How does the atmosphere trap heat?

• Through the greenhouse effect, where certain gases absorb and re-radiate infrared radiation, keeping the Earth's surface warm.

• By reflecting sunlight back into space, preventing it from reaching the Earth.

• Through the process of photosynthesis, where plants convert sunlight into energy.

• By creating a vacuum that holds heat close to the Earth's surface.

What is convection?

• A process of heat transfer in solids where particles vibrate in place.

• A process of heat transfer in fluids where warm, less dense material rises and cooler, denser material sinks, creating a circulation pattern.

• A method of energy transfer through electromagnetic waves.

• A technique used to cool down materials by exposing them to cold air.

How does deforestation affect the atmosphere?

• It decreases carbon dioxide levels in the atmosphere.

• It has no effect on the atmosphere.

• Deforestation increases carbon dioxide levels in the atmosphere, contributing to climate change and the greenhouse effect.

• It improves air quality by reducing pollutants.

What is the greenhouse effect?

• The process by which the Earth's surface cools due to the reflection of sunlight.

• The warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

• The phenomenon where plants absorb carbon dioxide and release oxygen.

• The increase in Earth's temperature due to deforestation and urbanization.

What is the role of carbon dioxide in the atmosphere?

• Carbon dioxide is a pollutant that harms living organisms.

• Carbon dioxide is a greenhouse gas that helps regulate Earth's temperature by trapping heat in the atmosphere.

• Carbon dioxide is a byproduct of photosynthesis that is released into the atmosphere.

• Carbon dioxide is a gas that has no significant impact on the atmosphere.

What are greenhouse gases?

• Gases that cool the atmosphere, such as oxygen and nitrogen.

• Gases in the atmosphere that trap heat, such as carbon dioxide, methane, and water vapor.

• Gases that are produced by plants during photosynthesis.

• Gases that are only found in industrial areas and do not affect the climate.

What is conduction?

• Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

• Conduction is the process of heat transfer through the movement of fluids.

• Conduction is the transfer of heat through radiation without any contact.

• Conduction is the process of converting electrical energy into thermal energy.

What is ultraviolet radiation?

• A type of electromagnetic radiation from the sun that can cause skin damage and eye damage.

• A type of visible light that is harmless to the skin.

• A form of radiation used in medical imaging.

• A type of radiation that only affects plants.
