What causes the high surface temperature on Venus?

• Large amounts of carbon dioxide in Venus's atmosphere traps heat.

• The absence of rain forests on Venus causes the high surface temperatures.

• The clouds in Venus's atmosphere cause high surface temperatures.

• Venus is the closest planet to the Sun, which causes it to have high surface temperatures.

Answer explanation

Large amounts of carbon dioxide in Venus's atmosphere traps heat, leading to high surface temperatures.

The shape of Earth's Orbit.
