What is the main requirement for a
resource to be considered renewable?
List examples of renewable resources.
Resources $100
Renewable resources can be replaced in a SHORT
amount of timeExamples: Soil, animals, water, oxygen, CO2, plants, wind, sun, ocean tides
Resources $200What is the main requirement for a
resource to be considered
nonrenwable? List examples of
nonrenewable resources.
Resources $200Nonrenewable resources
take a LONG time to be replaced (more than a lifetime to millions of years)
Examples: rocks, minerals, fossil fuels (coal, oil, natural gas), gold, diamonds, gems
Resources $3001. Geothermal (geo=Earth; thermal=heat) –
energy generated from heat preserved within the Earth’s crust (remember – we only dig into the crust – we can not dig as far as the mantle)
2. Hydroelectric (hydro=water) – energy generated from the force of water in rivers, dams, & ocean tides
3. Wind – energy generated from windmills on wind farms
4. Biofuel (bio=life) – energy generated from decayed plants & animals
5. Solar – collecting the sun’s energy in solar panels
Resources $400Pros: can be replenished in a short
amount of time & keeps us from using all of Earth’s fossil fuels
Cons: not all of them are clean for Earth (burning biofuels can cause pollution); most need special equipment to change the resource into energy we can use (can be very expensive)
Resources for $500Fossil fuels come from buried dead/decayed organisms changed by increased heat & pressure from rock layers (takes longer than a lifetime to MILLIONS of years to form) **If FF don’t have enough heat, pressure, & time then they won’t form**
Examples:CoalPetroleum/OilNatural Gas

The pictures show a method used to collect data in an investigation. Different kinds of materials were mixed with 100 grams of garden soil. An equal amount of water was added to each mixture. Which of these was this investigation designed to answer?
A How well each material mixes with garden soilB How well each mixture holds waterC How well each material supports plantsD How well each mixture keeps its texture when wet

Earth’s Clues for $300
Four soil samples of equal volume were put in funnels with filter paper. 200 mL of water was added to each sample and the water that flowed out the bottom of the funnel was collected and measured. What can you determine about the soil samples from the data?
A Soil sample R retained the most water.B Soil sample T was the driest soil.C Soil sample Q has more organic matter.D Soil sample S was about half sand.

A Soil sample R retained the most water. (Retained = kept water in soil – it has the smallest # so Soil R kept in the most water)B Soil sample T was the driest soil.C Soil sample Q has more organic matter.D Soil sample S was about half sand.

Layers settle in water based on the
density of the material. Silt would be the least dense &
the small rocks would be the most dense according to
this picture.

W-E-D 1 for $100
Weathering is the BREAKDOWN of the materials in Earth’s crust into smaller pieces (weathering leads to formation of new soil).**Weathering down of landforms usually takes a very LONG time (hundreds to millions of years)
W-E-D 1 for $200
Erosion is the process by which water, ice, wind, or
gravity MOVES fragments of rock and
soil
W-E-D 1 for $300
Deposition is the process by which sediments (small particles of rock) are laid down in NEW locations.
Ex: deltas & sand dunes
W-E-D 2 for $100
The river the rocks are in is smoothing out the rocks (river is weathering down
the rocks)
W-E-D 2 for $300 Where a river meets an ocean – sediments are deposited. What is this
landform called?
W-E-D 2 for $300 DELTA – remember…deltas are due
to the deposition (building up) of sediments in a new location
Misc. for $200NO, most glaciers are actually
brownish/white because as they’re moving they are picking
up tiny sediments from the ground underneath. Those sediments get stuck in the
glaciers so glaciers become less white with time.
Misc. for $300
Canyons get deeper due to the river flowing through it. The river breaks/weathers down rock and
then carries/erodes the sediments away.

Fossil clues:-what kind of environment used to be there
(desert, ocean, or forest)-what kind of animals used to live there-the climate in that area (based on the kinds
of animal fossils there)-what kind of food animals ate in that area
(based on the shape of their teeth)

Burning coal, oil, or natural gas to make
energy is an example of what kind of resource?
Grab Bag for $300
Burning coal, oil, or natural is an example of using Earth’s nonrenewable resources –
remember we want to conserve them. Once they’re gone – it will take hundreds to millions of years to get them
back!
