So what are the 4 branches of Earth Science again?

MAGO means “magician”Use this word to help

you remember the 4 branches of Earth

Science. . .

Astronomy

Study of objects beyond Earth’s atmosphere

Stars, Solar System, Galaxies

Meteorology

Studies the Air that surrounds the Earth

Layers of the Atmosphere, Weather Patterns, Seasons

Geology

Study of materials that make up the Earth

rocks, minerals, glacial movements

Oceanography

Study of Earth Oceans

Physical and chemical properties, sea floor activity

What shape is our planet?

Four Main SystemsThere are four main systems that we study in Earth Science

Each System is interdependent on each other

1) Lithosphere

2) Hydrosphere

3) Atmosphere

4) Biosphere

Inner Core

Outer Core

Mantle

Crust

asthenosphere

Mantle continues downward

Earth’s Layers

Lithosphere

Its the outer shell of the Earth

crust and upper part of mantle that is rigid

the squishy part of the mantle is the asthenosphere

Solid Soft Plastic

Asthenosphere

Hydrosphere

The water in Earth’s lakes, oceans, rivers and glaciers

97% of the Earth’s water is saltwater

3% Freshwater

HydrosphereFreshwater

Glaciers and Icebergs

Lakes Rivers

75%

Groundwater

24%1%

AtmosphereBlanket of gas that surrounds our planet

78% Nitrogen and 21% Oxygen

1% other random gasses and water vapor

BiosphereAll organisms on the Earth, even Humans

Most live in the 1st few meters of Earth Surface

Only planet with life

Also includes the habitats of organisms
