Each question below carries 10 marks. 1) How does the cryosphere help regulate Earth's temperature?

2) What kind of organisms are found in oceanic trenches? Describe.

3) Explain how an Estuary can support a wide variety of food webs.

4) List out and describe the factors that help meteorologists forecast weather.

ans 1 ; It also includes frozen rivers and lakes, which mainly occur in polar areas. The components of the cryosphere play an important role in the Earth's climate. Snow and ice reflect heat from the sun, helping to regulate our planet's temperature.

ans 2 ; Deep-sea trench, also called oceanic trench, any long, narrow, steep-sided depression in the ocean bottom in which occur the maximum oceanic depths, approximately 7,300 to more than 11,000 metres (24,000 to 36,000 feet). They typically form in locations where one tectonic plate subducts under another.

ans 3 ; The calm waters provide a safe area for small fish, shellfish, migrating birds and shore animals. The waters are rich in nutrients such as plankton and bacteria. Decomposing plant matter, called detritus, provides food for many species. ... This means the estuary must support a wide variety of food webs.

ans 4 ; Weather can be defined as the condition of the atmosphere at any given time and place. Weather conditions are determined by six major factors: air temperature, air pressure, humidity of the air, amount and kind of cloud cover, amount and kind of precipitation, and speed and direction of the wind.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
