Molly notices hot sparks rising from a campfire. She knows the sparks are hot, because they are red. Which best explains the hot sparks rising?

• The sparks are rising due to radiated heat.

• The sparks are rising due to heat being conducted.

• The sparks are rising, and heat rises, proving this is convection.

• The sparks are rising to replace warm air, so the sparks are convecting heat.

Which best describes the relationship between movement and friction?

• As the rate of friction increases, the rate of movement increases.

• As the rate of friction increases, the rate of movement decreases.

• As the rate of friction decreases, the rate of movement decreases.

• As the rate of friction decreases, the rate of movement is unchanged.

Which process allows green plants to control the amount of water stored in their leaves?

• photosynthesis

• condensation
