What happens to the energy from the Sun when it reaches the atmosphere?

• It is all absorbed

• It is all reflected

• Some is absorbed and some is reflected

• It turns into electricity

What role do greenhouse gases play in the Earth's climate?

• They reflect all heat back to space

• They absorb and re-emit heat

• They have no effect on temperature

• They decrease Earth's temperature

• There would be no change

• Earth would be too cold

• Earth would be too hot

How does the Sun's energy distribution affect the Earth?

• It only affects the oceans

• More heat at the poles than near the equator

• More heat near the equator than at the poles

• It is the same everywhere

What mechanism moves heat from the equator towards the poles?

• Ocean currents only

• Atmospheric pressure only

• Both atmosphere and oceans

• Solar panels

What happens in the tropics near the equator to aid heat movement?

• Snow falls

• Nothing special occurs

• Thunder clouds develop forcing warm air to rise

• Ice forms

What is the effect of rising air at the boundaries between atmospheric cells?

• No change in weather

• Increased solar radiation

• Low pressure often with rain or snow

• High pressure and fine weather

What does the Gulf Stream do?

• Stops ocean currents

• Decreases temperatures in Europe

• Cools the North Atlantic

• Moves warm water from the Gulf of Mexico northeastwards
