Intro to Earth Science
Which discipline of Earth Science is described as the study of the blanket of air surrounding Earth?
Meteorology
What is the imaginary line that is 0 degrees latitude?
The Equator
What property uses Moh's scale?
Hardness
This occurs when rocks are broken apart by living things
What is biological weathering
Two of the four natural processes that can move sediments
Copper is commonly used for what?
What is the study of things beyond Earth's atmosphere?
Astronomy
What is the imaginary line that is 0 degrees longitude?
The Prime Meridian
What property is the least reliable, but most easily observed?
Color
The three types of weathering
What are mechanical/physical, chemical, and biological
This type of erosion creates meandering rivers and deltas
What is water
This aquatic mammal will be 2-6 after beating the king of the jungle on Sunday
Who are the Dolphins
What is the study of identifying rocks, studying glacial movements, and Earth's history called?
Geology
The International Date Line or IDL
If something were described as metallic, you would be talking about this property
Luster
This occurs when chemical reactions dissolve or alter the minerals in rocks
What is chemical weathering
The real name for the "lead" in your pencil is
Graphite
If a tree is taking up water from the soil, name two spheres involved.
Biosphere (tree), Geosphere (soil), Hydrosphere (water)
Why do time zones not always line up perfectly with lines of longitude?
political boundaries
If a mineral can scratch glass (5.5), but does leave a streak on a ceramic plate (6.5), what must its hardness be on Moh's scale?
6
This occurs when rocks are broken apart by physical processes
What is mechanical/physical weathering
Dunes and rock pillars are created by this phenomenon
What is wind
This type of erosion formed the Great Lakes
What is glacial
____________ study creatures that inhabit salty water, measure physical and chemical properties of the oceans, and examine the effects of human activities on the oceans
Oceanographers
Which of these is closer to the Equator?
A: 68 degrees N
B: 43 degrees N
C: 38 degrees S
C: 38 degrees S
In order to be a mineral, it must not be living, or made from living things. The word for this is ________
inorganic
One of two factors that affect the rate of weathering
What are climate or rock characteristics
This type of erosion creates cirques (valley) and horns (peak)
This rock is more resistant to weathering compared to marble
Name each of the 4 spheres, and give an example of each.
Geosphere: All the solid land, rocks, minerals, and soils on Earth, from the surface down to the inner core.
Hydrosphere: All the water on Earth in liquid, solid, and gas forms.
Biosphere: All living organisms on the planet, including plants, animals, and bacteria.
Atmosphere: The thin layer of gases that surrounds and protects Earth.
How far away in degrees are these two towns, and by longitude or latitude?
Town A, 65 degrees N, 35 degrees W
Town B, 15 degrees S, 35 degrees W
80 degrees apart, latitude
What mineral property is described as a ratio comparing something's density to the density of pure water?
Specific Gravity
What is acid rain (chemical weathering)
Occurs when glaciers move over fractured bedrock incorporating it into the ice
What is plucking
