The atmosphere consists of (a) Gases only (b) Water vapour only (c) Chemicals (d) Gases and water vapours science

(d) Gases and water vapour

Explanation:

The atmosphere is a part of the Earth that contains predominantly gases or gaseous substances. In other words, the atmosphere is a combination of different gases, including water vapour.

Atmosphere is said to contain the following gases in the following proportion:

- Nitrogen (78%)

- Oxygen (21%)

- Argon (0.9%)

- Carbon dioxide (0.04%)

- Water vapour (1-4%)

Therefore, the Earth's atmosphere consists of many gases and water vapour.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
