Radio telescopes have to be much larger than optical telescopes because the wavelengths of radio waves are so much larger<span> than the wavelengths of visible light.
just search it up on Google . . .</span>
In the theory of natural selection, organisms produce more offspring that are able to survive in their environment
Explanation:
Answer:
c. Eolian
Explanation:
By observing the environment presented in the question above, we can identify the presence of many sand sheets and different types of dunes. These characteristics are directly related to Eolian Environments, which are those where the wind is the main means of transporting sediment and presents a predominance of sand, like the environment presented in the question. These environments are usually drier and have a low concentration of water.
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.
