(vi) What is air pressure?

please answer this question​

Answer 1

Answer:

the blanket of air which surrounds Earth is called atmosphere.

G(i) Two gases make up the bulk of the earth's atmosphere: nitrogen ( ), which comprises 78% of the atmosphere, and oxygen ( ), which accounts for 21%. Various trace gases make up the remainder.

(ii)A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone.

(III)Weather is the state of the atmosphere, describing for example the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy. ... Weather refers to day-to-day temperature and precipitation activity, whereas climate is the term for the averaging of atmospheric conditions over longer periods of time.

(iv)Relief rainfall occurs when air has been blown over the sea and is then forced up over an area of high land.

This causes the air to cool and the moisture in the air condenses and rain falls.

(v) Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth. The standard atmosphere is a unit of pressure defined as 1013.25 mbar, equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
