Earth Science 0403

Standard IV, Objective 3:  Dynamics of the Hydrosphere

Standard 4: Students will understand the dynamics of the hydrosphere.
Objective 3: Analyze the physical, chemical, and biological dynamics of the oceans and the
flow of energy through the oceans.

I Can Statements
a. I can research how the oceans formed from outgassing by volcanoes and ice from comets.
b. I can investigate how salinity, temperature, and pressure at different depths and locations in
oceans and lakes affect saltwater ecosystems.
c. I can design and conduct an experiment comparing chemical properties (e.g., chemical
composition, percent salinity) and physical properties (e.g., density, freezing point
depression) of freshwater samples to saltwater samples from different sources.
d. I can model energy flow in the physical dynamics of oceans (e.g., wave action, deep ocean
tides circulation, surface currents, land and sea breezes, El Niño, upwellings).
e. I can evaluate the impact of human activities (e.g., sediment, pollution, overfishing) on ocean
systems.
