Prepare for Soil Lab
1. Dig down about 6 inches
and get about half a bag of
soil.
2. Lay your soil sample out to
dry on a labeled paper
towel.
2. Put 35 ml of the soil into a
tube and add 15 ml water.
Shake for 1 min. Label and
set aside.
The Rock Cycle
How does the
lithosphere form?
Types of rock
Igneous
Sedimentary
Metamorphic
Igneous Rocks
Magma is pushed to the
surface by volcanoes..
Pools of magma cool
down slowly in the
crust to form igneous rocks.
Igneous rocks are
crystalline and hard to
break.
Smaller crystals form through fast cooling
– such as pumice.
- Wind, water and/or ice transport these
particles to floodplains and the sea by erosion.
- The pressure of many layers changes the
bottom layers into sediments.
Sedimentary Rock
• Forms from
sediment particles
that are deposited
by water, wind or
ice.
• Formed under great
pressure – no heat is
involved.
• Properties:
– Found in layers
– Often contains fossils
Metamorphic Rock
• Rock that started as
igneous or
sedimentary.
• Forms due to
immense heat
and/or pressure of
the earth’s crust.
• Properties:
– Crystalline
– Compressed
structure
Types of Rock- exploration
• Examine each set of rocks
• What characteristics are in common for
igneous rocks? Sedimentary? Metamorphic?
• With a partner: how does each type of rock
form? Summarize the rock cycle.
