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:
C. Magma from venus mantle erupted as lava.
Explanation:
A volcano is a landform which results from the eruption of molten rocks (lava) on the surface. Volcanic rocks are a special type of igneous rock that forms when molten rock cools and solidifies on the surface.
From the little description given, option C gives the best scientific explanation to the occurrence of the volcano on the surface of Venus. For a planet like venus which is presently not active and little to no movement occurs within the plates, the volcanisim must have occurred when the planet was relatively young and it must have been millions of years ago.
It is widely believed that Venus was geologically active in times past. Mantle generated lava must have solidified on the surface in times past to have formed the volcano.
Evaluating other options:
... Impact of space objects on Venus would lead to the formation of a crater which is a depression on the surface. The rock would be mostly metamorphic.
.... If water was ever present in Venus, they would have produced sedimentary rocks instead. The erosive power of water is not high enough to cut through the crust. Also, water would not aid the formation of volcanoes.
.... Heat is not enough to from volcanoes. Other factors are also in play.

Answer:
The loss of arctic ice negatively affects the sustainability of the human population.
Explanation:
About 68.7 percent of the water in the world is held at the poles as ice. The melting of the arctic ice will lead to a drastic increase in the amount of water in the sea, causing a rise in sea levels. The effect will be that countries close to the sea will get flooded with water. This will cause the deaths of thousands.
Most Islands such as the Caribbeans, Iceland, and Madagascar will be totally submerged in water as a result of this.
