Earth is the third planet from the sun and the only one known to support life, with a complex system of geology, oceans, and atmosphere. Estimated to be about 4.54 billion years old, its surface is continually changing due to tectonic movements, erosion, and volcanic activity. Earth science encompasses the study of its structure and environment, including various subfields like geology and ecology.

2. PLANET EARTH
• Planet Earth is the third planet from the sun
in our solar system and is the only planet
known to support life. It is a rocky planet
with a complex system of geology, oceans,
and atmosphere that enable it to host a
diverse range of living organisms, including
humans.
• The Earth is estimated to be about 4.54
billion years old and its surface is constantly
changing due to processes such as tectonic
plate movements, erosion, and volcanic
activity. The study of the Earth and its
environment is called Earth science,
including geology, meteorology,
oceanography, and ecology.

3. The Earth’s Structure is made up
of four different layers. It refers
to the arrangement of different
layers that make up the planet's
interior, characterized by distinct
physical and chemical properties.
Each layer has its distinct
characteristics and composition.
