Some of the sun's energy reflects off of the Earth.
Step-by-step explanation:
When sunlight reaches the Earth, it interacts with various surfaces and objects. Some of the sunlight is absorbed by the Earth's atmosphere, land, and oceans, warming them up in the process. However, not all the sunlight is absorbed; some of it bounces off these surfaces and is reflected back into space. This reflected sunlight is what we see as brightness or glare. So, when we say "Some of the sun's energy reflects off of the Earth," it means that a portion of the sunlight that hits the Earth's surface is not absorbed, but rather bounces back and goes back into space.
