Answer:
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.
Explanation:
The geological action of glaciers comprises erosion, transportation and deposition which together constitute what is known as glaciation. The geological action of glacier is mainly due to its flow.
Explanation:
after earth cooled down from being a large ball of molten lava , the water vapour in gaseous state turned into liquid and it poured rain for thousands of years filling all the oceans we see now and as the rocks were filled with salts and minerals the ocean became salty
The Biosphere is the zone of earth, land and air where life exists. It is a complex multilayered system that is typically broken up into 3 (not 5) distinct components. These are:
1. Lithosphere -this is essentially the land (the solid component of earth).
2. Hydrosphere - the watery parts of the earths surface including oceans, lakes, pools.
3. Atmosphere - the gas component enveloping earth supporting life, including the lower atmosphere and gases such oxygen, carbon dioxide, nitrogen.
1. While there is always the possibility of being an offset, the fact point that the increasingly industrialized nations with rapidly growing large populations are constantly using more and more energy and the trend seems that it will continue. These nations have industries that grow exponentially, as well as exponentially growing populations, thus providing lot of labor force. Unlike the developed countries, these countries don't bother with investments in renewable sources of energy, but they use strictly the fossil fuels, which will just make an even bigger environmental problem in the future.
2. The best strategies that can be used by these nations to not be such big consumers of the fossils fuels is that they invest, be it on their own or with foreign aid, into the renewable resources. Most of these nations have great potential for development of such energy sources. We can take Nigeria for example, which has lot of sunny days, as well as great hydropotential, so it can focus on these two for production of energy. Pakistan is a very windy nation, and it also has lot of sunny days, and on top of it has lot of uninhabited land that can be used, so it can focus on these two for production of energy.
