Materials such as soil and gravel that are carried by moving water, wind, or ice are called?
What is sediments

During our Hills and Valleys experiment, what did the water form or create as it was moving downhill? (To our land)
What is a widening valley
100
What is a sand dune? (what does it form)
What is a pile of sand that is deposited in one place, forming hills
100
A glacier moves rock and soil like a (wheelbarrow or bulldozer)
What is a bulldozer

True or false: erosion occurs when rock material is moved from one place to another by moving water, wind, or moving ice
What is TRUE!
200
Moving water, wind, and moving ice pick up and carry soil and other materials in a process known as?
What is erosion
200
What prevents a beach from washing away? This is a strip of land or rock built out into the water
What is a jetty
200
How does the wind's power seem to be related to its speed? (faster the wind speed...)
What is the faster the wind speed, the heavier the objects the wind can carry
200
Name two kinds of glaciers
What is 1) continental 2) valley

2 ways that water can help to weaken or break up rocks
What is
1) Through weathering: It can dissovle minerals in a rock. It can also seep into cracks in the rock, and with time freezing and thawing of that water causes the rock to break apart
2) Water in the form of waves can also break up rocks. When a wave hits the shore, it carries small rocks that rub against larger ones, causing small pieces of rock to break off
300
Rocks are broken into smaller pieces by the process of?
What is weathering
300
During our "At the Beach" Activity, How did the size of the waves affect the movement of the sand? (Think about big waves vs. small waves and how that affects the speed of how slow or fast a shoreline changes)
what is the smaller waves moved sand only a little at a time, which meant it would take a longer period to make a noticeable change. The big waves (from storms) can change a shoreline quickly
300
Wind blown sand can (erode, harden) rock surface?
What is erode
300
What is the main force that makes valley glaciers flow?
What is gravity
300
Would you build a house on a sandy beach or would you build it on a rocky shore? explain
What is rocky shore because a sandy beach might be more easily eroded, causing the house to collapse!
400
A huge mass of slow moving ice that forms over land is called?
What is a glacier
400
During our "At the Beach" activity, when waves hit the jetty what did it do to our sand and the shoreline?
What is it stopped the water from destroying the shoreline, which meant not as much sand was moved along the shoreline
400
Plants or valleys can act as windbreaks, which slow down the wind?
What is plants
400
What two places are continental glaciers found?
What is Greenland and Antarctica
400
How is weathering related to the process of erosion?
What is weathering is a part of erosion that breaks down rocks into smaller pieces. Erosion incldues moving the broken-down rock from one place to another.

1) A body of water that is partly enclosed by land, but has an opening called a mouth, connecting the water to the ocean is called?
2) A natural piece of land that extends out into the water is called?
1) What is a Bay
2) What is a Headland
500
How does moving water change the shape of our land?
(Think of weathering and erosion)
By breaking down rocks and carrying sediments from one place to another
500
Where winds blow steadily in the same direction, (dunes or glaciers) move?
What is dunes
500
What are signs that show that a giant ice sheet once covered an area?
What is u-shaped valleys, pointed peaks, sharp ridges, steep cliffs, lakes, and waterfalls.

List the six steps of "thinking like a scientist"
What is
1) Make observations
2) Ask a question
3) Make a hypothesis
4) Plan and do a test
5) Record and analyze
6) Draw conclusions
