Answer:
Option (4)
Explanation:
The ‘climate envelope model’ is defined as a part of a major dispersion model of species that uses the climate parameters in order to make a predictions of total space that a species occupies in an environment.
This models represents the areas of climate that are suitable for species (both plant and animals) to exist. The variables that are commonly used in the species distribution models are climate type, land cover area, topography of the area and some other variable that are related to the species distribution model.
Thus, it can be considered that this model describes the range that a species can inhabit.
Hence, the correct answer is option (4).
Very easy to look up but it is Eurasia
Answer:
Constructive wave is a wave that leads to the build-up of a beach, owing to the swash of the wave being more effective in moving material than the backwash. Usually, constructive waves are associated with low-energy conditions and a gentle offshore gradient.
Answer:
If contours are close together it indicates a <u>steep slope</u> and if they are apart it means a relatively gentle or <u>flat slope</u>.
Explanation:
Topographic maps were created to depict the relief features and type of terrain on the map. The use of contour lines drawn on a map is done to show the lines of equal height of elevation. These lines tend to remain constant. Also, there are three types of contour lines on a map i.e the supplementary, Index and Intermediate. The dark brown color is used to show lines of high altitude and light brown lines represent low altitude. The more close the line is the steeper is the wall and the far the lines are less is the compactness and more is the gap.
