What are the different types of rocks? Sedimentary Rocks

Slide 4
Sedimentary Rocks Sandstone Sedimentary rocks are little pieces
of our earth that have been washed and worn away by wind and water
for thousands and millions of years. Have layered appearance
because the materials that form them are deposited in layers.
Sedimentary rocks that are compacted contain rock particles such as
pebbles and sand. Limestone Gypsum
Slide 5
Igneous Rocks Igneous rocks are also called fire rocks and are
formed either underground or above ground. Some igneous rocks erupt
from volcanoes as lava or pumice. Others, like granite, form
underground magma chambers. Fine-grained igneous rocks include
Basalt. Volcanoes Obsidian Rocks Pumice Rocks Click before each of
the names to learn more about them!
Slide 6
Metamorphic Rocks Metamorphic is Greek for change of form. Are
rocks that have morphed into a different type of rock. These rocks
were once igneous or sedimentary rocks. Have a banded or layered
appearance. Metamorphic rocks are hard and strong. Gneiss Schist

Fossils Fossils are the only remains of ancient animals and
plants, traces or impressions of living things from the past
geologic ages. Fossils have been found on every continent on Earth.
The only direct way we have of learning about dinosaurs is by
studying fossils. Plant and animal fossils can be found in many
sedimentary rocks. Click on the dinosaur to find out how! Click

Slide 14
Objectives Students will explore the 3 main rock types. o
Sedimentary o Igneous o Metamorphic Students will learn how each of
the different rocks are formed and will examine a few examples of
each. Students will learn about fossils, how they are formed, and
how they are connected to past life forms.
