| Landforms | ||
| #1 | The earth's surface is constantly |
Very long time |
| #3 | Natural processes that occur on the earth's surface change the shape of |
Rocks |
| #5 | The two most important natural forces are |
Weathering |
| #2 | When rocks are physically broken down into smaller pieces by wind, water, ice or heat this is called |
Silt |
| #4 | When rocks are broken down by removing or altering elements that make up the minerals this is called |
Carbon dioxide |
| Weathering II | ||
| #1 | When carbon dioxide combines with rain a chemical change occurs they form |
Limestone formations |
| #3 | The end result of chemically weathered rock is |
Biological weathering |
| #5 | Biological weathering can occur by what two types of weathering? |
Water, ice or wind |
| #2 | Erosion is the breaking down....true or false? |
Sediment |
| #4 | What helps control erosion? |
Water, liquid or solid, as ice |
| Water Cycle | ||
| #1 | Rain, ice, snow or dew falls to the earth, this is called |
Evaporation |
| #3 | What provides energy in the form of heat which in turn drives evaporation? | The sun |
| #4 | This changes water, from water vapor (gas) to liquid water. |
Precipitation, evaporation, condensation |
| Final Question | |
| This organism removes the nutrients from the rock and reduce it to soil. This is called ? weathering | Chemical weathering |
