what is this answer telling you?
The Sun’s energy heats the surface of the Earth. This heating causes the surface water to evaporate. As the water cools it turns into clouds and eventually falls back to Earth as rain, snow, or ice. (aka The Water Cycle)• The Sun’s energy also heats the air causing currents.• In these ways, our weather is created.
The sun is a source of energy. Its energy drives the water cycle, winds, and weather.
___________ are materials that do not allow heat to pass or move through them easily
insulators
fun fact:
We have a lot of tests this week
cool idrc
Energy Stored in foods and fuels
Chemical energy
The sun also gives us (life) energy. Describe how this happens.
The Sun’s light energy is changed into chemical energy through photosynthesis in plants. Animals eat the plants and take in this chemical energy. Other animals (including humans) eat these animals, using this energy to stay alive.
