1. Introduction to Earth Science
Mr. Ross Brown
Brooklyn School for Law and Technology

2. Aim: What are the many areas of Earth Science?
14 Sept 2016
Do now: What are the different Sciences we will study in class this year?
Earth Science: the study of the Earth and the universe around it.

3. Geology
The study of the origin, history, and structure of the solid Earth and the processes that shape it.

4. Geology, cont. Some jobs for geologists:
Petrologist and Mineralogist: look for minerals and oil deposits
Seismologist: study and forecast earthquakes and volcanoes
Paleontologist: study the fossil record to understand the history of the Earth

5. Oceanography The study of the world’s oceans
Oceans cover 71% of the Earth's surface & contain 97% of the planet's water, yet over 95% of the underwater world is unexplored.* *

6. Oceanography, cont. Oceanographers study many things:
On research ships studying water quality
Some study waves, tides, or currents
Some study the ocean floor to understand the Earth’s history or to find resources
Some study marine plants and animals

7. Meteorology The study of the Earth’s atmosphere
Atmosphere: thick blanket of gases surrounding the Earth

8. Atmosphere

9. Meteorology, cont. Careers for Meteorologists:
Using technology (satellites, radar) to study variations in atmospheric conditions that produce weather.
Some measure & collect weather data
Some use these data to prepare weather maps
Some use these maps to forecast weather

10. Meteorology, cont.

11. Astronomy The study of the universe beyond Earth
Astronomy dates back thousands of years
Astronomers use land- and space-based telescopes, satellites, space probes
They study the Moon, planets, stars, galaxies, and the whole universe

12. Astronomy, cont.

13. Homework #1
14 Sept 2016
What are the 4 main branches of Earth Science?
What is Ecology? What is an Ecosystem?

14. Aim: What parts of the Earth will we be studying this year?
15 Sept 2016
Do now: How are the different regions of the Earth different? What words do we use to describe these differences?

15. Earth’s areas of study Geosphere: the solid Earth
Hydrosphere: the water on the planet
Atmosphere: the gases surrounding the Earth
Other scientists study Biology, the living world
Biology and Earth Science  Ecology
Relationships between living things and their environments

16. Ecosystem A community of organisms and the environment they inhabit
The largest is Biosphere: all life on Earth and the physical environment that supports it.

17. Homework What is a hypothesis? How will we test our hypotheses?
Come to class with a question to solve!
