Scientists call this the process of a rock being broken down into smaller pieces by water, wind, and natural forces.
What is a) deposition b) weathering c) plate movement d) erosion?
Wind breaking down walls is an example of this.
What is a) rapid change b) slow change c) no change d) chemical change?
You can tell this from the data in the table.
What is a) water carries the same amount of material on flat and steep slopes b) water running on flat slopes carries more material c) water running on steep slopes carries more material d) water running on steep slopes carries less material?
When you ran a full flow of water through your stream table, this result most likely occurred.
What is a) the stream ran deeper and straighter than with less water b) the stream ran less deep than with less water c) There was no change d) the stream carried less soil than with less water?
This is an example of a negative impact that can result from dam construction.
What is a) using water to produce electricity b) using the dam for boating, water skiing, and fishing c) changing the habitat for plants and animals in the area d) using water for irrigation for crops?
This process forms a river delta.
What is a) weathering b) deposition c) earthquake
d) plate movement?
This was the kind of weathering you were modeling when you blew over the sand pile.
What is a) sun b) rain c) wind d) snow?
This is the best way to show the data from this table.
What is a) Venn diagram b) model c) steam-and-leaf plot d) bar graph?
Sam poured water quickly through a stream table. Then she poured water SLOWLY through the stream table. This is what she most likely observed.
What is a) There was no change in how much sediment was eroded by the stream b) The stream carried less sediment and ran faster when the water was poured quickly c) the stream carried more sediment and ran faster when the water poured quickly d) the stream carried the sediment farther when the water was poured slowly?
This would be the best way for a scientist to predict how a town would be affected by a flood.
What is a) a model b) a Venn diagram c) a graph d) a pie chart?
This is an example of a rapid change.
What is a) mountain building b) earthquakes c) plate movement d) weathering?
Volcanoes are an example of this.
What is a) erosion of earth material b) deposition of earth material c) building up of new earth material d) weathering of earth material?
This is the name of the feature that is labeled # 3?
What is a) source b) bank c) mouth d) lake?
Sam poured water through a (nearly) flat stream table. Then she poured water through a stream table with a steep slope. This is what she observed.
What is a) the water flowed faster in the stream table with the flat slope b) there was no change in the speed of the water flow c) the water carried less soil when the slope was flat d) the water flowed faster when the slope was steep?
This would be the tool that scientists use to record data and to communicate (share) the results of their investigations.
What is a) Science notebooks b) stream tables c) a sand blaster d) email?
All of these are layers of the earth, except _______.
What is a) crust b) core c) mantle d) sediment?
Engineers built a dam on a river. This result would be a benefit.
What is a) the habitat for animals and plants will be destroyed b) flooding to most of the surrounding areas will be controlled c) an existing town located behind the dam will be flooded d) ancient archeological sites will be ruined?
This is the name of the feature that is labeled # 1.
What is a) lake b) source c) bank d) mouth?
When you sprayed water on the steep slope model made of aluminum foil, this is what you learned.
What is a) water moved from higher ground to lower ground b) after you sprayed, you could not tell where the water went c) water moved from lower ground to higher ground d) water soaked into the foil?
If the surface of the Earth is always eroding away, this is why it hasn't eroded away completely by now.
What is a) Not enough time has passed for it to erode away. b) Eroded earth materials are deposited somewhere else. c) Earthquakes and volcanoes create new hills and mountains. d) People change the Earth's surface as they build cities and towns. ?
Acid rain seeping into the ground to create caves is an example of this.
What is a) physical weathering b) erosion c) plate movement d) chemical weathering?
The movement of the Earth's layers cause all of the following except _________________.
What is a) volcanoes b) earthquakes c) rivers d) mountains?
You are planning to build a group of new houses along a stream. After watching four tests of floods on your stream table model, you have decided where to build your houses. This is where you would build your houses.
What is a) at the mouth of the stream #4 b) on the inside curve of the stream (#3) c) just below the dam of the stream (#1) d) along the outside curve of the stream (#2) ?
This best explains why some rivers might flow from South to North and others flow from North to South.
What is a) the plates under them are moving b) water moves from higher ground to lower ground c) their slopes are the same d) the wind blows them that direction?
A volcano erupted. When scientists looked at the volcano area, they noticed that a lake near the volcano had been moved. They think this is what happened.
What is a) the eruption sent a cloud of ash more than 12 miles high b) the volcano caused slow changes to the Earth's surface c) Scientists know that lakes move every 10-12 years d) The volcano caused rapid changes to the Earth's surface?
