4
The Rock Cycle

• Rocks are any solid mass of mineral or
  mineral-like matter that occurs naturally on
  Earth.

5
Types of Rocks

• 3 types of interactions with Earths water, land,
  and air
• Metamorphic heat and pressure
• Igneous cooling and solidification of lava
• Sedimentary compaction and cementation of
  sediments

6
The Rock Cycle (contd)

• Step 1 magma is formed by the melting of rock
  deep within Earths crust.
• Step 2 magma or lava cools and solidifies
• Creates Igneous Rock

7
The Rock Cycle (contd)

• Step 3 rocks on Earths surface are broken down
  by erosion and weathering into sediments
• Step 4 Sediments are compacted and cemented by
  pressure
• Creates sedimentary rock

8

• Step 5 Rocks are put under pressure, high
  temperatures, or fluids
• Creates metamorphic rock

9

• The rock cycle does not always occur in a
  specific order.
• Igneous rocks (Step 2) can directly become
  metamorphic rocks (Step 5).

10
Metamorphic rocks (Step 5) can be weathered and
eroded (Step 3). Sedimentary rocks (Step 4) can
be weathered and eroded (Step 3).
11
Source of Energy

• Igneous and metamorphic rocks internal
  processes (heat from Earths interior)

12
Sources of Energy

• Sedimentary rocks external processes (heat from
  the sun)

Exit Ticket 2/25/14 Imagine that you are going
on a rock climbing expedition. Take the
information you gathered from different texts
which involve the rock cycle and decide which of
the three types of rocks you would feel the
safest climbing and explain why you chose that
type of rock. Expand your answer to include why
you did not choose the other two types of rocks
as well.
