Weather Patterns

What are the two primary drivers of Earth's climate system?

• Ocean currents and volcanic activity

• Energy from the sun and the movement of heat in the atmosphere and oceans

• Earth's rotation and gravitational pull

• Greenhouse gas concentrations and cloud formation

What happens to the sun's energy when it reaches Earth's atmosphere?

• All of it is absorbed by the Earth's surface

• All of it is reflected back into space by clouds

• Some is absorbed, some is reflected, and the remaining heats the Earth's surface

• It is entirely converted into heat in the atmosphere

Which of the following are considered greenhouse gases that absorb heat in the atmosphere?

• Nitrogen and Oxygen

• Carbon dioxide, water vapour, methane, and ozone

• Argon and Neon

• Hydrogen and Helium

• Yes

• No

How does the climate system balance the uneven distribution of the sun's energy across the globe?

• By increasing volcanic activity at the poles

• By moving heat from the poles to the equator through the atmosphere and oceans

• By moving heat from the equator to the poles through the atmosphere and oceans

• By altering the Earth's tilt to equalize solar radiation
