The Study of Earth Science

Section 1-2

Earth Science

• The study of Earth and its place in the universe– Structure of Earth– Earth’s history– Earth in the solar system

Earth’s Structure System

1) Lithosphere – rocky outer layer

2) Hydrosphere – oceans, lakes, rivers, ice

Earth’s Structure System

3) Atmosphere – mixture of gases that

surround Earth

4) Biosphere – all the

living things

Earth’s Structure System

All four spheres work together as a whole.

Matter and energy move between all the parts of earth’s system

Earth’s History

Constructive (building up) forces and destructive (wearing down) forces have shaped the Earth for 4.6 billion years

Constructive forces Destructive forces

Earth in the Solar System

• Looks at how objects other than Earth move around the sun

Branches of Earth Science

• Geology

• Oceanography

Nature of Technology

• Technology –

How people change the world around them to meet their needs or solve practical problems

Nature of Technology

The goal of technology is to improve the way people live
