PACT Jeopardy Review Rocks and Minerals/Soils/Fossils 3-3.1Classify rocks (including sedimentary, igneous, and metamorphic) and soils (including humus, clay, sand, and silt) on the basis of their properties. 3-3.2Identify common minerals on the basis of their properties by using a minerals identification key. 3-3.3Recognize types of fossils (including molds, casts, and preserved parts of plants and animals). 3-3.4Infer ideas about Earths early environments from fossils of plants and animals that lived long ago. Slide 2 3-3.1 Classify Rocks/Soils Rocks classified into this group were once melted but have cooled and hardened. They may be glassy like obsidian or grainy like granite. WHAT are IGNEOUS rocks? Slide 3 3-3.1 Classify Rocks/Soils Rocks classified into this group were once melted but have cooled and hardened. They may be glassy like obsidian or grainy like granite. WHAT are IGNEOUS rocks? Slide 4 3-3.1 Classify Rocks/Soils Rocks that are classified into this group are made up of smaller bits and pieces of rocks called sediments that have been pressed and cemented together. Some, like limestone, even have bits of shells, skeletons, or other remains of plants and animals. Sandstone is another example of this type of rock. WHAT are SEDIMENTARY rocks? Slide 5 3-3.1 Classify Rocks/Soils Rocks that are classified into this group are made up of smaller bits and pieces of rocks called sediments that have been pressed and cemented together.

Slide 6 3-3.1 Classify Rocks/Soils Rocks that are classified into this group were once other types of rocks found deep inside the Earth. They were heated and pressured causing them to change into a new kind of rock. Sometimes the minerals in these kinds of rocks line up in rows or bands. Slate and marble are examples of this kind of rock. WHAT are metamorphic rocks? Slide 7 3-3.1 Classify Rocks/Soils Rocks that are classified into this group were once other types of rocks found deep inside the Earth.

Slide 8 3-3.1 Classify Rocks/Soils When we classify rocks we look at several things to help us decide how to group them. One is color. Another one is the luster such as whether the mineral is shiny, pearly, glassy, or dull. What do we call these things we observe that help us classify? WHAT are properties? Slide 9 3-3.1 Classify Rocks/Soils When we classify rocks we look at several things to help us decide how to group them. One is color.
