Answer:
The think the answer is solar radiation.
Explanation:
here, we gain the heat from the sun through a radiation. When it travels from the sun the harmful radiation are absorbed by ozone layer and heat enegry is provided to the surface of the Earth.

Distance is a scalar and displacement is a vector
Explanation:
Distance and displacement are two different quantities. Let's review them in detail:
- Distance is a scalar quantity (only a number followed by unit). Distance represents the total length of the path covered by an object during its motion. Therefore, it does not take into account the direction of motion, in its calculation.
- Displacement is a vector quantity, so it has a magnitude, a unit and a direction. Displacement is a vector connecting the initial position to the final position of the motion of an object. Therefore, in its calculation, the direction of motion must be taken into account.
Let's see an example in order to understand distance and displacement better.
Imagine a person moving 5 meters forward and then 2 meters backward. In this case:
- The distance covered by the man is just the total lenght of the path covered, therefore: 5 + 2 = 7 meters
- The displacement of the man is the distance between the initial and final position. Since the man moved 5 m forward and 2 m backward, his final position is 3 meters forward, therefore the displacement is 3 m in the forward direction.
