Earth Science Test 1 Review Sheet

  1. DENSITY
  1. Know how to find density given a mass and a volume.
  2. If mass = 90g and the volume = 30cm3calculate the density of the object.
  1. Know how to find density given a mass and 3 dimensions of an object.
  2. If mass = 54g, and the length, width, and height of a cube each equal 3cm, what is the density of the cube?
  1. Know what density really means and what will change it. Also when it will NOT change.
  2. As temperature of an object increases, volume ______and therefore the density ______
  3. As the pressure on an object increases, the volume ______and therefore the density ______
  4. Will changing temp. or pressure ever affect the mass? Why or why not?

______

  1. OBSERVATION VS. INFERENCE
  1. Know the difference AND EXAMPLES of an observation and inference.
  2. REMEMBER, observations use only the senses to make a statement about what is seen, heard, tasted, etc.
  3. Inferences are conclusions/predictions that are made about an object or event based on a set of observations.
  1. LOCATIONS ON EARTH’S SURFACE
  1. Earth’s surface has a giant graph placed on it to determine locations on its surface.

The X axis, or horizontal starting point is the ______.

A locations angle, or distance away from that line is measured in ______.

A location can either be ______or ______of the equator.

  1. The Y axis, or vertical starting point is the ______and runsfrom the ______to the ______. It is also measured in degrees and areas to the left of the line are degrees ______of the Prime Meridian, and areas to the right of it are ______.
  1. Recall the first method used by humans of determining latitude, using Polaris (The North Star)
  2. Can only be seen in the Northern Hemisphere because it is located out in space directly above what location on Earth? ______. So at that location you would need to look ______to see Polaris.
  • As you travel south toward the equator, the angle of Polaris above the horizon in the sky will gradually ______.

**** The angle of Polaris above the horizon is always equal to ______******

  1. If Polaris is 40 degrees above the Northern Horizon, the latitude is ______.
  2. If you are at the 14th parallel North of the equator, Polaris would be located where in the sky?

______

  1. What is the latitude of this observer?

Latitude = ______

  1. Remember how to adjust the time of day for changing time zones.
  1. If it is 8am in New York City, what time would it be one time zone to the west, in Chicago? ______
  2. If it is 1pm in Los Angeles, what time would it be two time zones to the east in Dallas? ______
  1. What is the shape of the earth, what tangible objects is it most similar to? ______
  1. MAPPING EARTH’ SURFACE
  1. Height above sea level is called ______.
  1. Lines that connect points of equal elevation are called ______.
  1. How can you tell which way a stream is flowing on a topo map?

______

  1. Know how to draw isolines/contour lines on a map (connect the dots, or go between points that are above and below the isolines value)
  1. Know how to draw a topographic profile. Practice below….
  2. Determine Contour Interval. ______
  3. Label axis with elevations from 380-540ft.
  4. Use strip of paper to mark every contour that intersects line A-A’ and label its elevation.
  5. Transfer elevations to profile on top.
  6. Connect the points on profile.

Remember:

 DO NOT let extra information on a test question confuse you.

Remember to use your reference tables as much as possible.

Use process of elimination strategy on multiple choice questions if you do not know the answer right away.
