Answer:
Ice Sheet - Shrinking in a glacier
Moraine - Rock piles left by glaciers
Countour Planting - One way to prevent soil erosion
Retreating - Continent Sized
Explanation:
Ice Sheet: Shrinking of ice sheets in a glacier is a result of the burning of fossil fuels that building up greenhouse gases in the environment and leading to global warming. When ice exposes to heat, it shrinks and melts.
Moraine: A moraine is defined as the debris or piles of rock left behind by a moving glacier.
Countour Planting: Contour farming or planting is a farming technique in which plants are grown in row patterns across a slope following its elevation contour lines. It prevents soil erosion by capturing at least twice the rainwater.
Retreating: Retreating is the process in which either ice melts or erode. Continent size can be affected by the retreating ability of glaciers.
Hence, the correct answer is:
Ice Sheet - Shrinking in a glacier
Moraine - Rock piles left by glaciers
Countour Planting - One way to prevent soil erosion
Retreating - Continent Sized
