Answer:
area of land dropping steeply towards deep ocean basins
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. ... The binding of a substrate to an enzyme active site is termed the "enzyme-substrate complex.
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.
High mountain and Desert are the climate zones can be found anywhere on earth no matter the latitude location
Answer: Option C
<u>Explanation:</u>
The tropical, temperate and the polar zones are only found on certain extent on the surface of the earth like tropic of cancer extends from 0 to 23.5 degrees, temperate extends from 23.5 to 66.5 degrees and polar from 66.5 to 90 degrees but mountains and desert are the ones which are found on almost the whole surface of the planet not considering the latitude of the planet.
It occurs when and where there is not enough water to meet both demands and those of ecosystems to function effectively.
