What is global warming?

Global warming is the gradual warming of the Earth's surface that has been seen since the pre-industrial era (between 1850 and 1900), and is attributed to human activity, particularly the burning of fossil fuels, which raises the levels of heat-trapping greenhouse gases in the atmosphere.

Global warming causes greenhouse effect and leads to ozone layer depletions which hamper the climate due to excessive use of carbon & its related element by means of heavy use of fuels in transportation & industrialization.

Therefore warming temperatures melts ice sheets and glacier, exposing a darker surface that absorbs more solar radiation. In response, the air warms even further.

Both longitude and latitude are angles measured with the center of the earth as an origin. A longitude is an angle from the prime merdian, measured to the east (longitudes to the west are negative). Latitudes measure an angle up from the equator (latitudes to the south are negative).

The latitudes are the parallel circles with respect to the equator reducing in length northwards and southwards and the poles are the points only. On the other hand longitudes are equal in length drawn from North Pole to South Pole with their intervals reducing towards poles

Explanation: HOPE IT HELPS...

Answer:
