 1.
What are the three main ideas that
Earth scientists use to guide their work?



 2.

The structure of the Earth system
The Earth’s history
The Earth in the solar system
What is a System?
A group of parts that work together as a
whole
3.What are the four parts
scientists divide the Earth into?
 4.

 5.

LithosphereEarth’s solid rocky outer layer
BiosphereAll living things
 6.

HydrosphereAll water bodies
 Earth’s
 7.

oceans, lakes, rivers, ice
AtmosphereOuter most sphere, mixture of gasses
surrounding the Earth
 8.
What is the mains source of energy for
the systems on Earth?


The SUN!
How does the sun provide energy?
 Radiation
(heat), the water cycle
 9.
How old do scientists believe the Earth
to be?

4.6 BILLION Years old!!!
Constructive and Destructive
Forces
 10.
What are constructive and destructive
forces?
 Constructive: shape the Earth’s surface
 Destructive: wear away Earth’s surface
 Give examples:


Plate tectonics building up mountains,
volcanoes
Erosion of mountains by wind, water
 11.


What makes up the solar system?
Sun, planets, their moons, rocks, ice
particles
Planets and moons move around the sun
The Branches of Earth Science


12. Name the five branches of Earth science:
Geology

Oceanography

The study of Earth’s atmosphere
Astronomy

The study of Earth’s oceans
Meteorology

The study of the solid Earth
The study of the universe beyond Earth
Environmental Science
The study of Earth’s environment and resources

Model:
Helps scientists study and understand things
that can not be observed directly
Models are used to represent complex
objects or processes.
Used in Earth Science by meteorologists
using models to study weather, computer
simulations to test hypothesis.
