Continental shelf-Gently sloping seaward extension of continents, Granitic composition, average
slope .01%, average width- 40 miles, depth at shelf break= 300-600 feet deep.
Deep ocean floor- AVERAGE DEPTH; 12,000 ft (2.5 miles)
Abyssal plain; extremely f
Erosional and Depositional Processes and Longshore current
What processes form our coastline?
Erosion by waves- Single most influential affecting the shoreline
1.) Hydraulic action- pounding of surf on rocks.
2.) Abrasion- scouring action of rock particl
Previously we looked at the air pressure belts and atmosphere circulation. Then we assumed that
the Earth stood still. However we all know that this is not true. The earth does not rotate every 24
hrs. The Earth spins counter clockwise on its axis once pe

1a. In order for an observer to face all possible directions on the horizon they would have to
turn 360 degrees. If you were facing north and turned eastward the angular designation of East
Uncertainty in measurement- No measurements are exact. A measured quantity is expressed by
stating all digits known as the uncertain digit, usually the last number in an equation or answer.
Precision- How close a set of values obtained from identical meas
Characteristics of Inner and Outer Planets:
Close to the sun, small size, high density (rocky), slow rotation
Larger planets spin faster, few moons with no rings
B. Outer (Jovian)- Gas Giants
Large size (99.5), low density (gaseous),
Matter is anything that has energy and mass. Chemistry studies the chemical reaction of energy.
Molecules- Stuff that makes up the world, thinking from a molecular structure perspective.
Chemical engineering and the pharmaceutical companies work
Empiricle Formula: The lowest number ratio of atoms of the elements in a compound. Example:
H^20^2 equals HO since it is in its simplilest form.
Example 2: C^8 O^18 can be converted to C^4 O^9. C4O9

Ocean Surface Circulation- Causes: Wind, Uneven heating of Earth, remember its curved
Gyres- Current gyres are closed loops of 4 ocean currents. These are strongly influenced by the
Coriolis effect. Coriolis deflects the prevailing winds 90 degrees to the
Earthquake Magnitude and intensity - The sudden release of energy, along the fault, that
produces shaking or trembling of the ground. Most occur at plate boundaries. Intensity is
qualitative, magnitude is quantitative. Of these many occur at convergent bo
