O It is the global interconnecting web of physical and biological phenomena
<span>o We use it because global change involves the transformations and modifications of physical and biological components of the Earth System through time. Unidirectional change results in transformations that never repeat, whereas cyclical change involves repetition of the same steps over and over again.</span>
Answer:
True
Explanation:
The individual grains from different classes of rocks (i.e., igneous, metamorphic, and sedimentary) develop by different processes. For example, a sedimentary rock might have individual grains of sand held together by a natural cement.
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:
The atmosphere is composed of a mix of several different gases in differing amounts. ... Nitrogen accounts for 78% of the atmosphere, oxygen 21% and argon 0.9%. Gases like carbon dioxide, nitrous oxides, methane, and ozone are trace gases that account for about a tenth of one percent of the atmosphere.
