Question

Select the correct answer.

Why are polar climates the coldest ones on Earth?
OA.
B.
O C.
O D.
Snow and ice have higher albedo.
Polar regions receive less direct sunlight as compared to other regions.
The polar regions never face the Sun.
There is very little vegetation, which results in less absorption of solar energy.

Answer 1

Polar climates are the coldest because they receive less direct sunlight, have higher albedo, and very little vegetation

Step-by-step explanation:

The correct answer is B. Polar regions receive less direct sunlight as compared to other regions. Due to the Earth's axial tilt, the polar regions are tilted away from the Sun for a significant portion of the year, resulting in less direct sunlight. This leads to colder temperatures in the polar climates.

Additionally, the presence of snow and ice with higher albedo in the polar regions contributes to the colder temperatures. Albedo refers to the reflectivity of a surface, and snow and ice have a high albedo, meaning they reflect a significant amount of the Sun's radiation back into space, rather than absorbing it and warming the environment.

Furthermore, there is very little vegetation in the polar regions, which means that less solar energy is absorbed through the process of photosynthesis. This results in less warming of the environment, contributing to the overall cold temperatures in polar climates.
