|---|
| Mudslide | Heavy rainfall reduces the forces holding soil on a hill |
| Earthquake | Horizontal forces move sections of the Earth's crust breaking the ground |
| Shield Volcanos | Are not high and erupt slowly (Hawaiian Islands) |
| Granite | Igneous rock that resists weathering |
| Ice weathering | Freezing ice expands forcing rock to break apart |
| Erosion | Increased by steep slopes on hills or mountains |
| Water weathering | Water can wear holes through rock |
| Rock cycle | Rocks come from volcanoes, erosion, and layering of sediments under pressure |
| Rocky Mountains | Large mountain range caused by the Earth's crust colliding |
| Volcano eruption | Escaping gases push upward and scatter dust particles into the atmosphere |
| Mountains | Built by two forces pushing towards each other |
| Rock cycle | One type of rock changing into another type |
| Oceanic deposits | Cause limestone to form |
| Granite | Rock used to build the capital building of Texas |
| Magma | Cools and hardens to form igneous rock |
| Metamorphic rocks | Melt in the earth's inner heat to form magma |
| Metamorphic | Type of rock that forms from long periods of heat and pressure |
| Rocks on the earth's surface | Will experience weathering and erosion |
| Uplifting | Causes bulges in the earth |
| Igneous rock | Metamorphic rock that rises to the earth's surface where wind, water and ice break it apart. |
| Composite Volcano | Formed from alternating quiet and explosive eruptions |
| Dormant | A volcano that does not show signs of eruption in the near future |
