PACT Jeopardy Review
Rocks and Minerals/Soils/Fossils
3-3.1
Classify rocks (including sedimentary, igneous, and metamorphic) and
soils (including humus, clay, sand, and silt) on the basis of their properties.
3-3.2
Identify common minerals on the basis of their properties by using a
minerals identification key.
3-3.3
Recognize types of fossils (including molds, casts, and preserved
parts of plants and animals).
3-3.4
Infer ideas about Earth’s early environments from fossils of plants and
animals that lived long ago.
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?
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?
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?

WHAT are SEDIMENTARY
rocks?
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?

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?
