Study Notes

Module 9: Energy Resources

All Earth processes require energy from various sources.
Natural disasters involve sudden energy release.
Thermal energy is heat energy from vibrating molecules.
Earth's energy sources are solar and internal (geothermal).
Solar energy is abundant and can be harnessed even in cloudy conditions.
Renewable energy (e.g., wind, geothermal, hydropower) is often called clean energy.
Wind energy uses wind turbine kinetic energy, either onshore or offshore.
Geothermal energy utilizes Earth's internal heat.
Hydropower energy comes from flowing water.
Non-renewable resources deplete over time and may last for many lifetimes (e.g., coal, petroleum, natural gas).

Module 10: Waste Management

Wastes are substances discarded after primary use, defective, or worthless.
Waste types include solid (domestic, commercial, industrial), and liquid.
Examples of solid waste: plastics, styrofoam, bottles, cans, papers, scrap iron, etc.
Examples of liquid waste: domestic washings, chemicals, oils, manufacturing waste water, etc.

Module 11: Energy Resources - Hydrosphere

The hydrosphere encompasses all Earth's water (97.5% saltwater, 2.5% freshwater).
Inland waters include lakes, rivers, and groundwater.
Watersheds/catchment areas are areas where inland waters drain.
Factors influencing water flow include topography, geology, climate, vegetation, and development.
Oceans are categorized as Pacific, Atlantic, Arctic, Indian, and Southern Oceans.
Ocean temperature varies with latitude and depth, with equatorial areas being warmer.
Ocean salinity (salt content) is measured by the amount of dissolved salts, affected by river flow.
Ocean circulation is the movement of seawater, including major surface and subsurface currents.

Module 12: Ground Water

Groundwater is water beneath the Earth's surface in saturated zones.
Subsurface water is water in the soil mantle above the water table.
Soil water zone is the area where plants absorb water.
Capillary zone is above the water table where capillary action draws up water.
Springs are where groundwater naturally flows to the surface.
Hot springs originate from heated groundwater.

Module 13: Oceanography

Oceanography studies the interaction between ocean life and environment.
Chemical oceanography studies seawater's chemical properties.
Physical oceanography examines energy transfer through water (waves, currents, tides, etc.).
Earth's hemispheres are categorized as land (Northern) and water (Southern).
Hydrology is the science of water.
Oceans (Pacific, Atlantic, Indian, Arctic, and Southern).

Module 14: Human Activities and the Environment

Human activities influence ecosystems positively and negatively.
Consequences of actions can be positive or negative.
Finite resources are resources that eventually deplete.
Interrelationships are the connections between Earth's resources and human actions.
Trade-offs are solutions with both positive and negative consequences.
Examples of human-induced environmental problems include population growth, over-consumption, direct resource extraction, pollution, and harmful atmospheric changes.
