Answer:
It's the 4th, as third is modified by the man.
Explanation:
- The Third atmosphere was a rearrangement of the plate tectonics and the evolution of atmosphere by the transferring of it to the oceanic basins. As the amount of oxygen in the atmosphere used to be more than 30% around 280 million years ago than the present.
- Rapid development of land plants and animals was caused due to this atmosphere and hence this atmosphere is now less than 21% and due to his influence or modification of man with his technological tools and techniques.
- The atmosphere is rapidly shrinking due to the greenhouse effect and global warming that is leading to the fifth atmosphere that may be like that of mars as devoid of gases and barren and dry with oceans running under the crust.
Answer:
The Tropic of Cancer borders the regions of <em>Mexico, the Bahamas, Egypt, Saudi Arabia, India and Southern China </em>while the Tropic of Capricorn borders the regions of <em>Australia, Chile, Southern Brazil and Northern South Africa.</em>
Explanation:
In order to learn more about the answer, let's consider describing what the Tropic of Cancer is and what the Tropic of Capricorn is.
Tropic of Cancer- This is also known as "Northern Tropic." It is said that at the time of its naming, the sun was positioned in the <em>Cancer constellation </em>(one of the constellations of the zodiac). It is located at 23.5 degrees north of the equator and runs through the regions mentioned above.
Tropic of Capricorn- This is also known as <em>"Southern Tropic."</em> It is said that at the time of its naming, the sun was positioned in the Capricorn constellation. It lies at 23.5 degrees south of the equator and runs through the regions mentioned above.

<u>Equator- </u>The imaginary line that divides the earth into the Northern and Southern Hemispheres.
Answer:
As the region is deforested, the topography, gravity, soil permeability and terrain slope will control the runoff, as well as the intensity of the rain.
Explanation:
Runoff occurs when water flows over a soil that is saturated, that is, soaked. What controls the runoff efficiently is the native vegetation of the place, however, when this area is cleared, the soil is completely at the mercy of saturation, causing the runoff to be controlled by topography, gravity, permeability of the soil and the slope of the terrain, as well as the intensity of the rain.
