Answer:
Rougher and darker
Explanation:
Isolation refers to the amount of energy per unit area and per unit time that arrives at a given location on the earth's surface. Heat stroke varies according to place, time of day and time of year.
When a layer of ice melts, a surface of the earth is exposed to sunlight. As this exposed surface used to be covered before, it did not receive the sun's rays efficiently and for this reason it represents a rougher and darker soil layer, which will increase the increase in the absorption of sunlight.
