Activity 2
The Earth’s Subparts and Connection
Introduction
Earth is sometimes called the “water planet” or the “blue planet” because seas cover more than two-thirds of its surface. Earth is the only planet or moon in the solar system with rain that falls from clouds, runs over the land, and collects in extensive oceans. It is also the only body we know that supports life.
Content
The four subsystems of the Earth are:
1. Atmosphere – the gaseous layer above the Earth’s surface primarily composed of different gases such as nitrogen and oxygen.
2. Biosphere – the zone of the Earth where all forms of life exist. This serves as the ecosystem of all living and non- living organisms.
3. Geosphere – the solid part of the Earth that consists the entire planet from the center of the core to the outer crust. It includes core, mantle, and crust of the Earth.
4.Hydrosphere – the water part of the Earth that includes oceans and glaciers.
