DO NOW!1) Name 2 renewable resources, 2
Nonrenewable resources, and 2 Perpetual resources.
2) What are the 2 major differences between traditional and alternative energy sources?
3) What are the 3 types of fossil fuels and how are they formed?
*Don’t forget to use your notes! That’s why you have them!
DO NOW! (answers)1) Renewable- Plants, Trees, Animals, Water.As long as they are not over used or made unusable to
humans.Nonrenewable- Oil, Coal, Gold, Natural Gas.Perpetual- water, wind, sunlight2) Traditional- Burns fossil fuels & produces air
pollution. Alternative- Uses natural resources and does not
produce air pollution (minimal at most)3) Coal-trees & plants buried in swampsNatural gas & Oil-animals in ocean died & buried
The Objective:
• SWBAT- Explain the consequences of human activities on the lithosphere (such as mining, deforestation, agriculture, overgrazing, urbanization, and land use).

Human Activity
Definition Impact Solutions
MiningDeforestationAgricultureOvergrazingUrbanizationOverfishing
Mining the extraction of valuable minerals or
other geological materials from the earth.Impacts: Habitat destruction, air & water
pollution, respiratory diseases
Deforestation the removal of trees to clear land for a non-forest use. (e.g. farms, ranches, or urban use)
Impacts: Increased erosion (washing away of top soil), loss of habitats & species
Agriculture (farming) the production of plants, animals for food, fiber, and other products used to support human life.
Impacts: water pollution from pesticides, fertilizers
Overgrazing when plants are exposed to excessive grazing for long periods of time, or without enough recovery time. (caused by livestock, overpopulation of wild animals, poor agriculture practices)
Impacts: Loss of biodiversity (variety of life)
Urbanization
the physical growth of urban areas as a result of global change.
Impacts: heat islands (reduces soil moisture & intensifies carbon dioxide emissions)
OverfishingTo deplete (use up) the supply of usable fish in a
certain area of water*Impacts: extinction of marine fish species, loss
of biodiversity, decline in fisheries*Aquaculture (potential solution!!): raises fish in
ponds or fenced areas of water; however, it requires wild fish for feeding, fish crowding occurs, may invade native habitats
MAKING NEWS!
• In groups I assign, you will research a topic about a human impact on Earth’s surface.
• Using the information from your reading and Text Book, your group will create a 2 minute News Story Poster to present to the class
Information you MUST include in your news story poster...15min prep
• A description of the activity you are researching.• Why it occurs.• The impacts this activity has on the Earth.• Most importantly: What potential
solutions/alternatives can your team propose?
*Winning presentation will receive a prize!!!
It’s up to us to take action!!

Homework
• Write a letter to President Obama. In your letter, explain how we can improve our environmental and quality of life. You need to support your argument. Use what you have learned over the past few days, including what you learned today about the negative impacts of our actions on the lithosphere.
Exit Ticket
• 1) Explain 2 negative affects of mining?• 2) How does deforestation affect the
environment?• 3) What is another name for sustainable
agriculture?• 4) What is the cause of over grazing? • 5) What is a Heat Island and where does it
occur?
