How does energy relate to the transportation and deposition of sediments?
Sediment is any solid material that is moved by a variety mechanisms, transported and deposited in a new location. Movement of sediment is generally termed as erosion. Sediment varies in size. It can be as small as a grain of sand or as large as a boulder. Generally, sediment is composed of rocks, minerals, and the remains of plants and animals.
Energy required for transportation and relocation of sediment is provided by
- Air power. Wind can move dirt across a plane during a dust-storm. Sand dunes are created when rocky sediment is worn down by wind and the sediment is deposited in one place.
- Movement of Ice. Movement of glaciers transports extremely large pieces of sediment, which is frozen into a glacier. As the ice sheet moves across the landscape or melts sediments are deposited elsewhere.
- Water. Rain water carries large amount of soil from hills along-with it to plains. River Water can wash medium and small sediment into a delta. Stronger flow of the water has the ability to transport more sediment, in terms of size and quantity.
Waves, tides and ocean currents are agents for sediment relocation.
- Gravity. Falling of rocks and large boulders from the top of hills due to gravity also facilitates erosion.
