Ultraviolet radiation is the primary cause of sunburns
The earliest forms would be plants and other life like that, and current day would be mostly humans and animals and a lot of plants are disappearing
The axis of the earth is tilted (ANSWER IS C). The equator is heated more than other areas because the sun's rays hit it directly.
As you move north or south of the equator, they fall slantingly or obliquely.
When summer is in the south and vice versa, the heat also changes with the earth's rotation.
The tropic of Capricorn and the tropic of Cancer alternately get direct sunlight.
Due to the uneven heating of the earth, wind and ocean currents are created, supporting life.

A. 12.5 m/s.
The average speed is defined as the relationship between the displacement made by a body and the total time it took to perform it.
The formula that will allow you to calculate the average speed is:
v = d/t, where d is the traveled distance and t the time it took to travel the distance.
We hace to convert 4 minutes to second:
(60 s/1 min)*(4 min) = 240 s
So, the average speed is:
v = 3000 m/240 s
v = 12.5 m/s
