| A | B |
| weathering | causes Earth to constantly change and happens gradually |
| acid rain | mix carbon dioxide and rain together |
| landslide and avalanche | rapid erosion |
| lava | molten rock coming from the volcano |
| fault | It wasn't me or break in Earth's crust |
| erosion | washing away of land by water |
| deposition | laying down pieces of rock and building up Earth's surface |
| building a seawall | stop erosion |
| glacier | mixture of rocks, soil, and ice; erodes the land |
| volcanic eruption | changes Earth's surface by covering it with rock and ash |
| volcano | forms at a weak spot where magma is forced upward |
| earthquake | sudden movement that causes Earth's crust to shake |
| epicenter | point on Earth's surface that is directly above the focus of the earthquake |
| ice | causes physical weathering |
| delta | formed from deposition |
| volcanic eruption | can affect the climate |
