Answer:
B. distance of the deposit from the source.
Explanation:
The grain size of sedimentary deposit can indicate the distance of the deposit from the source. This is because, when sediment is transported by water, the sediment becomes victim of abrasion. As abrasion occurs, the edges of the grains of deposit are reduced, eventually leading to a rounder shape. However, this process can vary based on the distance of the deposit, the method of transportation and the energy characteristics of the transportation medium.
The answer to this question is 4.9 Millimeters
Answer:
Density is one of the most factors that play a key role in plate tectonic activities. Some of the ways in which density is important in the field of plate tectonics are as follows-
- The convergent plate boundaries are responsible for the creation of a subduction zone, where the high-density lithospheric plate subducts below the less dense one. It is because the heavier plate is comprised of heavy minerals thereby forming heavier rocks as a result of which its density increases. Due to these differences in density, there occurs a subduction zone.
- The divergent plate boundary forms where two plates move away from one another. This type of plate motion is responsible for the eruption of magma on the seafloor. As the plates diverge, the lithosphere becomes eventually thin, and with more progressive spreading, the magma comes out to the seafloor. This is because the hot magma is less dense, and forms convection cells as they rise upward. This is how the density helps in the upwelling of magma at the mid-oceanic ridge in a divergent plate boundary.
- When there collide two plates of equal densities, then it gives rise to the formation of huge mountains, because neither of them is heavy to get sink. So it uplifts the crust, forming a sandwich-type pattern.
Answer:
It releases bbbles of carbon dioxide
Explanation:
Answer:
The answer is: Continental drift on the Earth is caused by circulating convection currents in the deep interior.
Explanation:
Numerous studies and observations have shown that plate tectonics is due to the circulatory motion of convection currents within the Earth’s mantle which is below the Earth’s crust, and is as deep as 2,890 km. The motion of the convection currents are propelled by heat which rises and transports gas, and liquids or molten substances, and causes the crust (landmass, and ocean floor) to move.
