pollution from industry and transportation, and many other activities all
contribute to the damage of the envir

Main Idea 1:
Ecologists study environments at different levels of organization.
Ecosystems and the Biosphere
What do animals and plants need to survive?
Why are frogs showing up with mutations?
How does pollution affect plants?
Does Oil drilling affect humans? Other animals?
Is the Earth getting warmer? How will it affec
THE EARTHS HYDROSPHERE
o The Earths liquid water constitutes the hydrosphere.
o The vast majority of Earths water is in the oceans (salt water), with smaller, but
geologically important, quantities of fresh water in lakes, rivers, and ground
Should be about some problem that encourages enthusiasm (for
you) and interest (for others)
Is often generated from the thought what weve got now/from the
past isnt quite right/good enough we can do better
Introduction to Earth Science
o Essential Questions
What does an Earth Scientist study?
What information do various maps give to an Earth Scientist?
How do Earth Scientists (and all scientists) seek knowledge?
o Overview of Earth Science
The Structure of the Earth and Plate Tectonics
o Structure of the Earth
o The Earth is made up of 3 main layers:
o The Crust
This is where we live!
The Earths crust is made of:
How do we know what the Earth is made of?
PEDOSPHERE THE QUALITY OF THE SOIL
o Determine it by :
Grain (particle size in the soil) soil of sorts
The quantity of humus soil type
The quantity of moisture soil type
Sites on earth soil type
Fertility soil type
Acidity and alkaline
o In the developed world. . We no longer honor our relationship to the soil. . . Soil
has simply become one more resource - a substance necessary for crop
production and for holding up buildings. . .

Volcanic Eruptions and Hazards
o What is a volcano?
A volcano is a vent or 'chimney' that connects molten rock (magma) from
within the Earths crust to the Earth's surface.
The volcano includes the surrounding cone of erupted material.
o How and why do
What are Earthquakes?
o The shaking or trembling caused by the sudden release of energy
o Usually associated with faulting or breaking of rocks
o Continuing adjustment of position results in aftershocks
o What is the Elastic Rebound Theory?
