Question

18. Distinguish between lithosphere and hydrosphere. Give any three points of difference.
​

Answer 1

Answer:

Your answer is:-

Explanation:

The Lithosphere is simply the scientific name for the Earth's crust It is the solid, outer part of the Earth whose thickness ranges from 42 miles to 52 miles. The Hydrosphere is the sphere composed of all the water on/below/above the surface of the lithosphere.

Answer 2

$lithosphere ✌️$

• The Lithosphere is simply the scientific name for the Earth’s crust It is the solid, outer part of the Earth whose thickness ranges from 42 miles to 52 miles.
• The crust and upper mantle are distinguished on the basis of chemistry and mineralogy.
• The earth’s crust is not a homogeneous substance; it has different layers of rocks including sedimentary rocks on top, granitic and metamorphic rocks in the middle, and basaltic rocks on the bottom.

$hydrosphere ✌️$

• The Hydrosphere is the sphere composed of all the water on/below/above the surface of the lithosphere. For example: ON includes oceans, lakes rivers wetlands etc.. BELOW includes groundwater and interstitial water.. ABOVE refers to water in the atmosphere in a liquid or gaseous state.
• It has been estimated that there are 1,386 million cubic kilometres (333,000,000 cubic miles) of water on Earth.[6] This includes water in liquid and frozen forms in groundwater, oceans, lakes and streams. Saltwater accounts for 97.5% of this amount, whereas fresh water accounts for only 2.5%. Of this fresh water, 68.9% is in the form of ice and permanent snow cover in the Arctic, the Antarctic and mountain glaciers; 30.8% is in the form of fresh groundwater; and only 0.3% of the fresh water on Earth is in easily accessible lakes, reservoirs and river systems.[6]

• The total mass of Earth's hydrosphere is about 1.4 × 1018 tonnes, which is about 0.023% of Earth's total mass. At any given time, about 20 × 1012 tonnes of this is in the form of water vapor in the Earth's atmosphere (for practical purposes, 1 cubic meter of water weighs one tonne). Approximately 71% of Earth's surface, an area of some 361 million square kilometers (139.5 million square miles), is covered by ocean. The average salinity of Earth's oceans is about 35 grams of salt per kilogram of sea water (3.5%).[7]
