You have 4 flower pots. Pot #1 is filled with clay soil. Pot #2 is filled with medium grained potting soil. Pot #3 is filled with small gravel and pot #4 is filled with large pieces of loose rock. If you pour a glass of water into each pot....which one will allow the water to flow through the FASTEST?
What is Pot #4 (then large rock pieces offer the least resistance to the water)

Weathering is: * the movement of worn down rock * the settling of rock pieces in a new location * the breaking down of rock into smaller pieces
What is : the breaking down of rock into smaller pieces
100
Erosion is: * The movement of weathered rock * The breaking down of rock into smaller pieces * The settling of rock due to gravity, glaciers and water
What is : the movement of weathered rock
100
Which of these is a renewable resource? * coal * oil * water * natural gas
What is water (water is renewed in the water cycle)
100
What are the 3 R's:
What is : reduce, reuse, and recycle
200
Which layer of soil is MOST affected by weathering and erosion? * the bedrock * the topsoil * the subsoil
What is : topsoil
200
Which of the following is most likely to weather rocks on a mountain? * leaves decaying on the rocks * snow melting on the rocks * water freezing and melting in the cracks of the rocks * dew evaporating on the rocks
What is : water freezing and melting in the cracks of the rocks (this process slowly causes the rocks to crack more and break apart into smaller pieces)
200
Most canyons are the result of erosion caused by: * a volcano * a hurricane * a river * an earthquake
What is : a river
200
Fossil fusel are classified as non-renewable because they ... * can be easily recycled * come from deep within the Earth * will never run out * take a long period of time to form
What is : take a long period of time to form (fossil fuels take millions of years to form from the remains of once living plants and animals)
200
Which of the following has the greatest effect on the ability of soil to hold water? * the age of the soil particles * the texture of the soil particles * the size of the soil particles * the color of the soil particles
What is : the size of the soil particles (the larger the particles (gravel or sand) the less water will be retained. The smaller the particles (clay) the more water will be retained)
300
The top layers of soil are important because they: * make walking easier * give plants nutrients * prevent earthquakes * protect the bedrock
What is : gives plants nutrients
300
When water, wind, or ice moves sediment from one place to another it is called: * percolation * deposition * erosion * weathering
What is erosion
300
There is a heavy rainstorm on a farm. Which is most likely to wash away following the rain: * the gravel on the driveway * soil piled up on the side of the house * stepping stones in the garden * soil under the grass lawn
What is : soil piled up....
300
Which of the following is NOT a renewable resource? * plants * air * coal * animals
What is : coal (coal is a fossil fuel and takes millions of years to form deep underground)
300
Decaying plant and animal waste form a substance in soil called humus. What layer of soil contains the most humus? * bedrock * topsoil * subsoil
What is : topsoil

Ms. Nolan decided to test how much water three different types of soil would hold by putting the soil samples into funnels and then pouring water through them and observing how much water then collected in a beaker below. The beaker below the sand collected the most water, however the beaker below the clay did not collect any water. Few plants would grow in the clay because: A. The water would run through too quickly or B. the water would not reach the roots of the plant
What is B: the water would not reach the roots of the plant (because the wet clay is so dense and heavy)

A student is conducting an experiment using the streaming tables. He is testing to see how the size of rocks on a hill affects the amount of dirt that would wash away when water flows down the hill. In order to complete this experiment which variable must be changed. (a variable is a part of an experiment which may be different each time) * the amount of water used * the slope of the hill (streaming table) * the size of the rocks on the "hill" * the type of dirt on the "hill"
What is the size of the rocks (the experiment is specifically about comparing how rock size affects erosion...therefore the size of the rocks must be changed each time)

A big storm brings heavy rain to each of the following environments: a grassland, a desert, a forest, and a rocky mesa (a mesa is a flat plateau-like feature). Which environment would most likely suffer the most damage from erosion following the rain?
What is a desert (the loose sand is most likely to wash away)
400
Earth's supply of oil is running out. Which of the following could produce more oil? * Metals bubbling up from below the surface * rocks melting below the surface * plant and animal remains becoming buried for millions of years * water dissolving underground minerals
What is : plant and animal remains......

Materials and substances found in nature and used by people for a variety of reasons are called:
What are natural resources

Ms. Anderson has four soil samples and wants to find out which one absorbs moisture the best. In order to complete her experiment each soil sample must: * have soil from the same place * be given different amounts of water * have different soil types * be tested by the same person
What is: have different soil types
500
You are conducting an experiment with a stream table. What variable could you change to REDUCE the amount of erosion in the stream table? * Decrease the slope of the stream table so both ends are flat * Increase the amount of water poured on the stream table * Pour the water onto the stream table faster * Remove any rocks that are in the stream table
What is decrease the slope... (by reducing the slope you minimize the pull of gravity on the soil)
500
Following a heavy rain, soil at the top of a hill is carried as mud to the base of the hill. What processes are involved in the movement and piling up of the mud? * weathering and deposition * weathering and erosion * erosion and deposition * evaporation and condensation
What is erosion and deposition (erosion is the movement of the soil by the water and deposition is the relocating of the soil/mud from its previous location)
500
What will most likely happen in the future if people continue to use fossil fuels at the same rate as today? * People will discover how to renew fossil fuels * People will need to create more fossil fuels * Fossil fuels will gradually disappear * People will have more fossil fuels in the future
What is : fossil fuels will gradually disappear

When soil holds water well....the water does NOT pass through quickly. A student pours water into four different soil samples and measures the volume of water that passes through each one. The results are shown below: Sample 1 : 21 ml of water passed through Sample 2 : 16 ml of water passed through Sample 3 : 18 ml of water passed through Sample 4 : 12 ml of water passed through Based on these results....which soil sample holds water the BEST?
What is Sample 4 (It had the LEAST amount of water pass through which meant it was HOLDING the most)
