
The Earth is the third planet from the Sun, and the fifth-largest of the eight
planets in the Solar System.

The greenhouse effect is the heating of the surface of a planet or moon
due to the presence of an atmosphere containing gases that absorb and emit
infrared radiation.

Water vapor is the gas phase of water.

Radiation describes any process in which energy emitted by one body
travels through a medium or through space

The equator is the intersection of the Earth's surface with the plane
perpendicular to the Earth's axis of rotation and containing the Earth's
center of mass

A spectrometer is an instrument used to measure properties of light over a
specific portion of the electromagnetic spectrum, typically used in
spectroscopic analysis to identify materials.
Introduction
The atmosphere of Earth is a layer of gases surrounding the
core Earth that is retained by Earth's gravity.
Role of Earth atmosphere:
 absorbing ultraviolet solar radiation
 warming the surface through heat
retention
 reducing temperature extremes
between day and night.
 oxygen in the atmosphere, is needed by
all living organisms for respiration.
•Troposphere
•Stratosphere
•Mesosphere
•Thermosphere

Conclusion
 Modern methods of research have allowed the
person to learn many details of a structure and
chemical composition of an atmosphere.
 But this is remains a lot of unknown in a science
about an atmosphere, people continue to learn it.
