The lithosphere is the outermost sphere of the solid Earth, consisting of the crust and the upper part of the mantle. The lithosphere is largely important because it is the area that the biosphere (the living things on earth) inhabit and live upon.
If it weren't for the tectonic plates of the lithosphere there would be no change on Earth. Tectonic plates shift due to convection currents lower down in the mantle, and this can cause the formation of mountains, the eruption of volcanoes, and earthquakes. While this can be devastating in the short-run, long term benefits are the formation of new plant life, the creation of new habitats and encouraging adaptation.
It is also the source of almost all of our resources, and is rich in elements like iron, aluminium, calcium, copper and magnesium, which humans have used for tools and machinery for millennia.
When the biosphere interacts with the lithosphere, organic compounds can become buried in the crust, and dug up as oil, coal or natural gas that we can use for fuels.
In combination with the atmosphere and hydrosphere (water), it provides a stable source of nutrients for botanical life, which produce glucose that higher organisms use for sustenance.
Answer:
The correct answer is D
Explanation:
During the 20th century, there was an increasing interest in the environment. The impact of human activity on the environment has been observed locally since centuries. Pollution of canals and chimneys in crowded urban areas etc were all causes of concern.
However, with a better understanding of our earth and increase in Medical knowledge of the 20th century, we could observe how our activities were having a global impact on the ozone layer and the melting ice caps.
Evidence was also provided on how human health was affected by this. The use of fossil fuels was not only directly damaging to the atmosphere, it was also dangerous for humans e.g. carbon monoxide produced by car emissions.
Answer:
Areas or regions with low sea level or at sea level are called lowlands.
Lowlands are formed by deposition of lava through water, wind, or soil erosion and it has been said that such plains are more fertile for farming as compared to other high sea-level plains.
At Lowlands, people get opportunities for employment and the economy of the nation can be boosted.
For example, Lowlands of Scotland.
Farmers growing paddy or rice are getting the main benefits of Lowlands.
Lowlands have a suitable environment for many agricultural products.
Farmers can develop dairy farms and mountain farms.
