EARTH SCIENCE

 

                

 

EARTH SCIENCE are the fields of study concerned with the solid Earth, its waters, and the air that envelops it. They include the geologic, hydrologic, and atmospheric sciences with the broad aim of understanding Earth's present features and past evolution and using this knowledge to benefit humankind.

 4 MAIN BRANCHES

There are 4 major branches of earth science, with many other smaller branches . The four major are geology , oceanography, astronomy and meteorology.

Why do we study earth science

contributions to society, by: understanding climate change and its dramatic consequences. monitoring geohazards and predicting volcanic eruptions and earthquakes. discovering and managing the world's resources: hydrocarbons and precious minerals.

IMPORTANCE

It is an integrated study of the Earth's history, composition, and structure, its atmosphere and oceans, and its environment in space. Knowledge of Earth Science is important because most human activities are related to interaction with the planet Earth

The knowledge gained and the services provided by earth scientists help society cope with its environment in many ways. Their knowledge about the structure, stratigraphy, and chemical composition of the earth's crust helps us locate resources that sustain and advance our quality of life.

USES

Typically, Earth scientists use tools from geology, chronology, physics, chemistry, geography, biology, and mathematics to build a quantitative understanding of how Earth works and evolves. Earth science affects our everyday lives. For example, meteorologists study the weather and watch for dangerous storms.

 

Earth science is made of many branches of knowledge concerning all aspects of the Earth system. The main branches are geology, meteorology, climatology, oceanography, and environmental science. Astronomy uses principles understood from Earth to learn about the solar system, galaxy, and universe.
