Question

imagine earth covered entirely in dark - colored rock. how would this affect earths temperature?
sunlight would bounce off the rock without affecting earth.
earth would absorb more sunlight and likely heat up.
earth would reflect more sunlight and cool down.
the color of the surface wouldnt change anything.

Explanation:

Dark - colored surfaces have a lower albedo (reflectivity) compared to light - colored surfaces. They absorb more sunlight. If Earth was covered entirely in dark - colored rock, it would absorb more of the Sun's energy, leading to an increase in temperature.

Answer:

Earth would absorb more sunlight and likely heat up.
