  1. ROCKS & SOIL A PRESENTATION BY CHLOE THORPE

  2. IGNEOUS ROCKS Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks. Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.

  3. Examples of igneous rocks

  4. Sedimentary rocks Sedimentary rock is formed by mineral and other materials sitting in water for an extremely long time. While the minerals and other materials are in the water, they will have various things put pressure on them. After being exposed to these conditions for so long, it forms into sedimentary rock.

  5. Examples of sedimentary rock

  6. Metamorphicrocks Igneous rocks form from the solidification of lava or magma. If it forms intrusively, or within the earth, the rock will have large crystals. Granite is an example of such a coarse-grained igneous rock. If the rock forms extrusively, or on the earth's surface, it will have fine-grained crystals. Obsidian is an example of a fine-grained igneous rock.

  7. Examples of metamorphic

  8. SOIL • The upper layer of earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains

  9. FIVE DIFFERENT TYPES OF SOIL

  10. ARE ROCKS AND SOIL DIFFERENT ? YES!! AN EASY DEFINITION IS Rock is one object. and Soil is a mixture of rocks (rather small rocks: dirt), water, minerals, bacteria, plant, animal, fungi matter etc.

  11. Erosion affects rock and soil Erosion causes include - gravity, rain, flooding, wind, drought, deforestation, farming, flowing ice Which effects the rock and soil by desertification, additional sedimentation, loss of habitat, infertile soils, increased use of soil conditioners and fertilizers, water pollution

  12. EFFECTS of erosion!!!!!!!
