Parts of Earth
What substance is the Hydrosphere made out of?
Water
Will a rock with a density of 0.3 g/cm3 float or sink in water? (Water as a density of 1.0 g/ml)
Float; it is less dense than water
While on a field trip to a large lake in NY State, an observer recorded four statements about this lake. Which statement is an inference?
a. a log is floating in the lake
b. the water is clear enough to see the bottom of the lake
c. the lake was formed by glacial action
d. the surface temp of the lake is 18.5 degrees C
c. the lake was formed by glacial action
True or false: lines of latitude run from pole to pole
False. Lines of longitude run from pole to pole
What does a contour interval tell you?
How much the elevation changes by
What is the most abundant element by mass and volume in the lithosphere?
Oxygen
What is the density of a rock which has a mass of 35 grams and a volume of 7.0 ml?
5 g/ml
Object A has a density of 0.8g/cc and object B has a density of 1.2g/cc.
Infer what will happen when the objects are placed in water.
Object A will float, object B will sink.
What two hemispheres are we in?
"Isoline" means...
a line connecting points of equal value
Would a cloud be part of the hydrosphere, lithosphere, or atmosphere?
Atmosphere
A rectangular prism has a density of 3 grams and dimensions that are 1cm x 3cm x 2cm. What is the mass of this object?
At 7am, the air pressure was 1,012 millibars. By 11am, the air pressure had dropped to 1,004 millibars. What was the rate of change in air pressure?
2.0 mb/hr
Which directions do lines of latitude use, and which directions do lines of longitude use?
Latitude use North and South. Longitude use East and West
If you see contour lines creating a circle with tick marks going towards the circle, that means...
That feature is a depression
What is the lowest layer of the atmosphere called?
Troposphere
A rock sample has a mass of 16 grams and a volume of 8 cubic centimeters. When the rock is cut in half, what is the density of each piece?
2.0 g/cm3
If the greenhouse effect causes the Earth's average temperature to increase by a total of 6 degrees F between the years 1930 and 1990, what is the rate of temperature change in degrees per year during that time?
0.1 degrees/year
Lines of latitude are measured in degrees ranging from
90 degrees N to 90 degrees S
Describe how close or far apart contour lines should be when showing a gradual slope.
Far apart
In what layer of the atmosphere is the air temperature the warmest?
Thermosphere
As you gain altitude, what happens to the density of the air?
decreases
The tide is coming in during the hours of 9am - 12pm. During this time, the water level rises 7 feet. What is the rate of change in the water level?
2.3 ft/hr
What's another way of writing 42.5 degrees?
42 degrees 30 minutes (42 degrees 30')
Describe the rule of V on a contour map
When a river crosses a contour line, the lines create a bend (v). The point of the v points to higher elevation.
