Question

E. Write short notes on the following.
1. Nitrogen in the atmosphere
2. Global warming
3. Ozonosphere
lonosphere
please answer in detail​

Answer 1

Answer:

1.Nitrogen is an element that can combine with itself or with other elements to make different compounds. For instance nitrogen gas, N2, is a compound made when two nitrogen atoms form a chemical bond. It makes up about 80% of the atmosphere, while oxygen gas, O2, makes up a little less than 20% of the atmosphere.

2. Global warming is that the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) thanks to human activities, primarily fuel burning, which increases heat-trapping greenhouse emission levels in Earth's atmosphere.

3. Ozone protects the Earth from harmful ultraviolet (UV) rays from the Sun. Without the Ozone layer in the atmosphere, life on Earth would be very difficult. Plants cannot live and grow in heavy ultraviolet radiation, nor can the planktons that serve as food for most of the ocean life.

The ionosphere is the part of the atmosphere that is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth.

Answer 2

Answer:

Hey mate here is your answer

Explanation:

Nitrogen in Atmosphere

nitrogen is the most abundant element in Earth's atmosphere: approximately 78% of the atmosphere is nitrogen! Nitrogen is important to all living things, including us. ... Nitrogen is necessary for our food supply, but excess nitrogen can harm the environment..

Global warming

Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

Oznosphere

ozonosphere - a layer in the stratosphere (at approximately 20 miles) that contains a concentration of ozone sufficient to block most ultraviolet radiation from the sun. ozone layer. layer - a relatively thin sheetlike expanse or region lying over or under another.

ionosphere

ionosphere (/aɪˈɒnəˌsfɪər/) is the ionized part of Earth's upper atmosphere, from about 48 km (30 mi) to 965 km (600 mi) altitude, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation.ionosphere is important because it reflects and modifies radio waves used for communication and navigation.....
