Geologic Time:

Given a geologic cross section, appropriately order the sequence of events from oldest to youngest.  Example Cross-Section:

Define the Principle of Original Horizontality

Define the Principle of Superposition

Define the Principle of Cross Cutting Relationships

Ocean Processes:

Describe where a sea wall is installed, and what it is used for.

Describe Longshore current, and details of how it affects the distribution of beach sand.

Define what a groin is and where how it is oriented.

Describe what a barrier island is, how it is oriented, and why building on one may be an issue.

Be able to properly identify the following features:  spit, tombolo, sea stack, sea arch

Define a submergent and emergent coast line, and how a global change in sea level may affect each.

Describe how most waves originate.

Describe how what influences tides.

Density Currents and Convection

Describe how convection works, and provide at least 3 examples.

Explain how the density currents lab worked, and what you understand from that exercise.

Earth-Sun-Atmosphere Relationships

Describe why the earth is unevenly heated by the sun, and how this affects the development of ocean and weather systems.

Given a figure of the Earth – Sun Relationship, describe the expected seasonal variability for different regions of the earth.

Weather Basics

Understand the features of a cold front and a warm front.

Why type of front system and resultant clouds are most likely to produce thunder storms?

Define/Describe the Coriolis Effect and its effects on the distribution of weather systems around the globe.
