1.1 What is Earth Science?

Earth Science = study of Earth and its neighbors in space.

Geology = study of Earth

Physical Geology = study of materials that make up the Earth and the processes that shape Earth.Examples: Rocks, soil, climate, volcanoes, weather, earthquakes, erosion, mountains, minerals, ice, etc.

Geology = study of Earth

Historical Geology = study of the history of Earth (not human history).Examples: geologic time, fossils, plate tectonics, etc.

Oceanography = study of the Earth’s oceans.

Meteorology = study of the atmosphere, weather and climate.

Astronomy = study of space and planets.

See pg 4.

Formation of EarthNebular Hypothesis = bodies of our solar system evolved from a big rotating cloud called the SOLAR NEBULA.

combine to make 4 inner planets (Mercury, Venus, Earth and Mars).

Lighter particles combine to make 4 outer planets (Jupiter, Saturn, Uranus

and Neptune).Key Concepts & Vocabulary pg 2

1.2 A View of Earth

Earth’s 4 Major Spheres Hydrosphere = water

Atmosphere = air

Geosphere = land

Biosphere = living th

ings

Hydrosphere (Water)

Cycles continually from surface to air and back to surface.

Oceans (salt waters) make up 97% of all water on earth.

Most important water on earth is fresh water (only 3%).

Reaches over 100 km above Earth.

90% is within 16 km of Earth.

Provides air we breathe.

Protects us from the Sun’s UV rays.

Provides systems for climate and weather.

Atmosphere (air)

Geosphere (land)

Made of the Core, the Mantle, and the Crust.

The Core is very dense and very heavy.

The Mantle is melted lava.

The Crust is thinnest at the oceans and thickest at the continents.

Geosphere (land) cont.

Lithosphere = crust and outermost mantle.Asthenosphere = innermost mantle that the crust flows on.Lower mantle = less fluid, stronger rock.

Biosphere (living things)

Living organisms interact with the earth’s systems to create the world that we know. Without them the Earth would be a very different place.

Made up of all living things (plants, animals, microscopic organisms, etc.)

Plate Tectonics

Earth’s crust is broken into sections that slowly flow on top of the liquid mantle.

Plate Tectonics = movement of earth’s plates.
