When the lines are close together on a contour map, it tells us that the slope is:
steep (a more difficult climb)
100
In what ways does Earth's atmosphere protect us?
- it acts like a blanket (many layers that keep the temperature just right for life)
- it protects us from harmful UV/solar rays

A sample of Olivine has a mass of 210g and a volume of 15cm³. What is its density?
D = M/V (Density = mass divided by volume)
14 g/cm³
100
Which metamorphic rock below is foliated and how can you tell?
Gneiss- we can clearly see the lines that formed- this rock was formed under inetnse heat and pressure.
100
A gradual slope on a contour map will be shown with lines that are ______ apart from each other.
farther (easier climb)
200
Which sphere(s) are represented in this photo?
All of them! :)
Hydropshere (lake)
Atmosphere (sky- includes gases)
Geosphere (sand, rocks, hills/mountains)
Biosphere (grasses)
200
This image is an example of an object/substance made up of ______.
crystals- a solid made up of repeating particles
(snowflakes, salt, sugar)
200
A(n) ______ is important to many living things since it is an extra supply of water that is naturally stored underground in rock layers for use.
aquifer
200
What is a contour map?
A map that shows us an area, marked with lines that give us information about elevation (height).
200
What type of luster does this mineral have?
dull, flat
300
Name a few properties that we can look at when trying to identify a mineral.
color, luster, hardness, streak (powder color), chemical reactions
300
A tsunami is an example of a ______ force because it breaks down/flattens land and causes significant damage.
desconstructive
300
As a _____ air front comes in, cool air swoops toward a warm air mass and attempts to push it out of the area.
cold
300
________ currents rotate heat evenly within an area. This prevents one spot from being much warmer than another.
convection
*think of a convection oven, a boiling pot of water, the movement of tectonic plates- ALL of these model convection- heat circles in a steady motion
300
The two most important gases in Earth's atmosphere are:
oxygen
nitrogen
*both help to sustain life :) Yay!
400
What part of the water cycle fits this description:
"the extra water from precipitation that doesn't soak into the soil"
runoff
400
This type of air mass is called ______ and it is traveling in a ____ direction.
- occluded (warm air is stuck between the cold air)
- northwest (we can tell, as it is pointing/heading in that direction)
400
How has plate tectonic movement impacted the location of fossils, plants, minerals & mountain chains over time?
Plate movement has occurred over millions of years. These MASSIVE portions of rock "carry" our continents, allowing them to slowly move. There is evidence that fossils, parts of mountain chains, etc have moved because they are now scattered all over our globe.
400
How are seismic waves helpful to scientists?
These waves are able to travel into Earth and when they do, they bend in ways that prove different substances & different temperatures exist in places we can't physically get to.....yet :)
400
According to Mohs scale of mineral hardness, what minerals can a steel nail scratch?
Anything from 6 down: Feldspar, Apatite, Fluorite, Calcite and Gypsum
500
Satellites that communicate to one another help determine movement & location is known as:
GPS
500
What causes air pressure to lower as we increase altitude?
Air molecules spread farther apart the higher up, which lessens the pressure upon us.
500
The two main sources that give energy to Earth are:
Heat from Earth's ________.
Heat from the the _______.
interior
sun
500
This image represents a(n):
delta- (an area where sediments are desposited -dropped- over time, as a river or stream meets a larger body of water)
*Recall that sediments are a mix of gravel, silt, sand, pebbles and other tiny particles
500
According to this map, what area(s) seem to experience the most rain and why might this be?
Upper WEST coast (WA area) & SE coast (FL, MS, LA). It could be b/c these locations are right by large bodies of water. This causes a lot of moisture to move into these areas during certain times of the year.
