Download Rock Cycle {PowerPoint}

TAKS Objective 5
The student will demonstrate an
understanding of earth and space
systems.
TEKS Objective: 8.12
The student knows that cycles exist in Earth
systems. The student is expected to
A
analyze and predict the sequence of
events in the lunar and rock cycles.
Prior Knowledge
• TEKS 6.6 C – Students identify forces that
shape the feature of the earth including
uplifting, movement of water, and volcanic
activity.
• TEKS 7.14 B – Student analyze effects of
regional erosional deposition and
weathering.
Learning Objectives
The student will be able to predict the events in the rock
cycle.
The student will be able to diagram and explain the rock
cycle.
All rocks are heavy.
True or False
A heavy piece of rock?
Think again!
All rocks are hard.
True or False
False
• Chalk
• Pumice
• Talc
Rocks never change.
True or False
False
• Rocks are changed by processes such as:
– Melting
– Pressure
– Heat
– Weathering and Erosion
Teacher Background
Igneous rocks are formed when magma
cools.

Melting
Sedimentary rocks are formed when
layers of earth have been deposited in
the bottoms of bodies of water. Over
time these layers are pressed together
forming sedimentary rocks.

Weathering and Erosion
Metamorphic rocks were once
sedimentary or igneous rocks that have
been placed under tons of pressure and
heat.
