WRITE NOTES! Convection is the process of heat transfer by the circulation or movement of a liquid or a gas. Conduction is the transfer of heat between two stationary entities. Radiation is the transfer of hear or energy through rays of various wavelengths. Read those definitions and think to yourself if those are correct. Condensation is the correct answer, but notes should be needed during your studies.
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:
The three criteria of the IAU for a full-sized planet are: It is in orbit around the Sun. It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape). It has “cleared the neighborhood” around its orbit. ^v^
Answer:
A categorical grant is used for a specific purpose, or category, for state or local spending. (Ex: natural disaster, airport building, crime fighting) that depends on state's population. Block Grants are given for general purposes that the states can use as they see fit (welfare, public health).
The answer would be D) Aridity.
