| A | B |
| Percolation | water travels down |
| Capillarity | Water ttavels up and sideways |
| absorption | Water stays in |
| Evaporation | water changes from liquid to gas |
| Clay | smallest particles, high absorption |
| Gravel | largest particles, high percolation |
| Sand | High capillarity |
| Topsoil | large amount of organic matter |
| Chemical weathering | atmosphere changes substance |
| Physical weathering | Atosphere makes particles smaller |
| Erosion | Soil carried away |
| Hypothesis | possible explantion |
| Manipulated variable | Changed |
| Responding variable | what is being affected and observed |
| Pores | Tiny holes |
| Lithosphere | Rock layer of Earth |
| Hydrosphere | water layer of Earth |
| Atmosphere | Air layer of Earth |
