Arctic ice plays an important role in cooling the earth. What evidence from the text best supports this statement?

А. In the last 30 years, more than one-third of the ice that appears in the Arctic during the summer has melted away.
B. Arctic ice reflects the sun's light.
C. When Arctic ice melts, it reveals more of the darker-colored land or ocean
water.
D. Darker-colored land absorbs the sun's light, causing the climate's
temperature to increase.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
