EVERYDAY SCIENCE

Detailed explanation-1: -Glaciation. As glaciers move across a landscape, they alter the terrain and carve out unique formations. This process is called glaciation, and it is responsible for many of the most recognizable landscapes on Earth.

Detailed explanation-2: -Gravity is the cause of glacier motion; the ice slowly flows and deforms (changes) in response to gravity. A glacier molds itself to the land and also molds the land as it creeps down the valley. Many glaciers slide on their beds, which enables them to move faster.

Detailed explanation-3: -Glacial motion can be fast (up to 30 metres per day (98 ft/d), observed on Jakobshavn Isbræ in Greenland) or slow (0.5 metres per year (20 in/year) on small glaciers or in the center of ice sheets), but is typically around 25 centimetres per day (9.8 in/d).

Detailed explanation-4: -Slow changes of Earth’s surface include the movement of the continents, uplift, weathering, erosion, and deposition. It has taken billions of years for the continents to assume their current shapes and positions.

Detailed explanation-5: -Most glaciers creep along at a pace that’s too slow to detect with the naked eye (about a foot a day). But sometimes conditions are just right to cause glaciers to surge. forward at speeds up to 100+ feet per day!
