Do Now: Rocks

2.
List the three main types of rocks AND how they form.
1.
Igneous- forms from lava or magma (melted rock above or below surface)
2.
Metamorphic- formed from heat and pressure (at times appears squished)
3.
Sedimentary- formed from pieces of other rocks or minerals through chemical or physical changes
For each type of rock (I, M, S), list and DESCRIBE the subcategories for each AND provide an
example from the power point for each.
A.
B.
C.
Igneous
a.
Intrusive- forms from magma INSIDE the earth
b.
Extrusive-forms from lava on the exterior of the earth (volcanoes)
Metamorphic
a.
Foliated- has crumpled lines or lanes
b.
Non-foliated-no crumpled layers
Sedimentary
a.
Clastic- made of pieces of sand and/or pebbles of pieces of rocks and minerals
b.
Chemical – made from evaporation process or chemical changes of a mineral
c.
Organic- made of up once living material (fossil fuel or has fossils in it)
