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).
Answer:
of rising air that is part of cell that originates at the equator.
Explanation:
Deserts are regions of the world that receives little to no precipitation all year round. Most deserts are known to be hot during the day and very cold at night. Deserts are typically lifeless with little no biodiversity of organisms.
Most deserts of the world are usually found around 30 degrees north and south of the equator because of the rising air masses which are a part of the global circulation. At the equator warm air laden with moisture rises and moves away due to their density and pressure. As they leave they equatorial region, they drop their moisture to form clouds. The air then becomes cold and dry as it moves towards the pole from the equator. It eventually sinks as it approaches the tropics of the cancer and capricorn. This dry and cold air is what leads to the formation of desert. Dry and cold air moves on the surface and does not provide rainfall.

They are quick and easy to set up and take up little space on a wagon or other modes of transportation. This is important because herders are constantly moving their livestock from place to place and cant stay in one area for too long.
