Download Chapter 3 – Rocks

Today’s Objective:
What is the Rock Cycle ?
Do Now –
How are rocks related to minerals?
Rocks
- Is any solid mass of mineral or minerallike matter that occurs naturally.
The three major types of rocks are:
1) Igneous rocks
2) Sedimentary rocks
3) Metamorphic rocks
The Rock Cycle
- Shows how rocks
change from one
type to another
because of the
interactions with
water, air, and
land.
ESRT pg 6
Define weathering, erosion, deposition,
magma, and lava as you watch the video.

Important Vocabulary
Weathering – is a process in which
rocks are physically and chemically
broken down by water, air, and
living things.
Erosion - transportation of
material.
Deposition - When an agent of
erosion (water, wind, ice, or gravity)
lose energy and sediments drop back
to the ground
Important Vocabulary
Lava – Magma that
reaches the surface.
Magma – is molten
material that
forms deep
beneath the
Earth’s surface.
Energy for the rock cycle comes from
Internal Energy
Processes driven by heat from Earth’s
interior are responsible for forming
both igneous and metamorphic rocks.
External Energy
Weathering and the movement of
weathered materials are external
processes powered by energy from
the sun & produce sedimentary rocks.
