1. Introduction to Earth/Environmental Science

2. What is Earth Science? Earth Science
The name for the group of sciences that deals with Earth and its neighbors in space.

3. Earth Science Areas of Study
Astronomy
Study of objects past the atmosphere
Ex: Stars, moon, comets
B. Meteorology
Study of the atmosphere
Processes of weather and climate
 Ex: clouds, rain, hurricanes
C. Geology
Study of materials that make-up the Earth
Processes that form and change those materials
Ex: rocks, minerals, earthquakes, volcanoes
D. Oceanography
Study of the oceans
 Ex: trenches, marine animals

4. What is Environmental Science?
The study of how humans use resources and the affect it has on the Earth

5. What Environmental Science deals with?
Renewable Resources
Plants, animals, water, wind
Nonrenewable Resources
Coal, oil, natural gas
Population Growth
Environmental Problems
Pollution, global warming
Natural Hazards
Flooding, droughts, earthquakes

6. Scientific Inquiry Hypothesis Theory Law
Stating a possible explanation
Educated guess
Theory
Extensive tested hypothesis and widely accepted by the scientific community
Still can be proven wrong
Law
99 % true
Law of Gravity

7. The Science and Engineering Practices
Asking Questions and Defining Problems
Developing and Using Models
Planning and Carrying Out Investigations
Analyzing and Interpreting Data
Using Mathematics and Computational Thinking
Constructing Explanations and Designing Solutions
Engaging in Argument from Evidence
Obtaining, Evaluating, and Communicating Information

8. Measurements Length /Distance How long something is Unit
m, km, cm, mm
tools to measure length: meter stick or ruler.
Temperature
How much heat an object has (Molecular motion)
C˚, F ˚, K
Tools - Thermometer

9. Mass how much matter is in the object Unit
g, kg, mg
Tools – balances, triple beam balance, and electronic scale

10. Volume How much space an object takes up Unit L, mL, cm³, cc(ml)
Tools: graduated cylinders and rulers
Volume of a regular object (block)
L x w x h
Volume of Liquids
Use graduated cylinders
Volume of irregular objects (rock)
Water displacement with a graduated cylinder

11. Measurement Cont. Density Mass per unit volume Unit Formula
g/ml or g/cm³
Formula
D = m/v
Hint: Density of Water = 1 g/mL

12. Mapping: TWO Main Parts
Latitude
Distance in degrees North or South of the Equator
Circles the globe east to west
Longitude
Distance East or West of the prime meridian
Circles the globe north to south

13. Major Lines on Earth Prime Meridian Equator 0º Longitude
To the right is East Hemisphere
To the left is West Hemisphere
Passes through Greenwich, England
Equator
0º Latitude
Halfway between the North and South Pole
North of it is the Northern Hemisphere
South of it is the Southern Hemisphere

14. Using Latitude and Longitude
