Answer:
D. Distortion.
Explanation:
In Geography, topography can be defined as the shape and structure of the Earth surface. Thus, a flat map is used to graphically describe this features.
Generally, elevations are represented on maps by lines of contour, which typically connect points having the same elevation. Also, elevations are shown on a physical map by using bands of color to connect points. In Geography, elevations are represented or measured in feets or meters.
Contours can be defined imaginary lines used for connecting locations that are having similar elevations on the Earth's surface. These contour lines are typically used for modeling the three-dimensional shape of the Earth surface in a map.
Hence, the changes in shape, size, and position of features that occur when representing the Earth on a flat map take place because of distortion.
Answer:
Explanation:
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
Answer:
the decrease of biodiversity and species
Explanation:
Measured by weight, or biomass, wild animals today only account for four percent of mammals on Earth, with humans (36 percent) and livestock (60 percent) making up the rest.
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.
Latitudes and the earth's radius are used to measure distances.
