__FREEMAN ES SOL 5

Mrs. Freeman's SOL REVIEW #4 - EARTHS RESOURCES AND HUMAN INTERACTIONS

QuestionAnswer
Much of our knowledge of the solar system is a result of space exploration efforts.
Technology has vastly improved how we explore space, such as telescopes, planetary orbiters, and landers/rovers.
Apollo 11 was the 1st manned landing on the moon. Neil Armstrong was the 1st man on the Moon.
The Hubble Space telescope has improved our knowledge and understanding of the Universe.
Ores are useful and profitable.
Common ore minerals are pyrite, magnetite, hematite, galena, graphite, and sulfur
Virginia resources include limestone, coal, and gravel.
Renewable resources can be replaced by nature at a rate close to the rate at which they are used.
Renewable resources include Solar power, hydroelectric power, geothermal power, vegetation, water, and soil.
Nonrenewable resources are renewed very slowly or not at all.
Nonrenewable resources include Nuclear energy, coal, oil, and minerals.
The Earth's Water Supply is renewable but also finite – which means there is only a limited amount.
Coal Evolution from softest to hardest- Peat, Lignite, Bituminous, Anthracite
In Virginia, major rock and mineral resources include coal for energy, gravel and crushed stone for construction, silica for electronics, zirconium and titanium for advanced metallurgy, and limestone for concrete.
Earth’s freshwater supply is finite
Geological processes, such as erosion, and human activities like waste disposal, can pollute water supplies.
The major watersheds in Virginia are the Chesapeake Bay, Gulf of Mexico, and North Carolina Sounds.
Estuaries are areas where salt water mixes with fresh water
The Chesapeake Bay. Is and estuary – where fresh and salt water mix.
Estuaries waters include variations in salinity and high biological activity.
Chemical pollution and sedimentation are great threats to the well-being of estuaries and oceans.
The oceans are environmentally and economically important.
The impact of human activities, such as waste disposal, construction, and agriculture, affect the water quality within watershed systems and ultimately the ocean.
Pollution and overfishing can harm or deplete valuable resources.
Human activities such as burning fossil fuels have increased CO2 levels.
The ability of Earth’s atmosphere to absorb and retain heat is affected by the presence of gases like water vapor and carbon dioxide.
High CO2 levels produce the Greenhouse effect.
CFC's (chlorofluorocarbons) are decreasing the ozone levels of the upper atmosphere.
