Question of the Day• This is a 2 part question.

• 1. What type of rock makes up 90% of Earth’s crust?

• Igneous rock

• If igneous rock makes up 90% of Earth’s crust how did other rocks form to make the remaining 10% of Earth’s crust?

• Weathering & erosion helped make new types of rock as well as processes like EQs and subduction.

Igneous Rocks

Igneous Rocks

• Igneous come from the latin word ignis, meaning “fire”

• 90 % of Earth’s crust is made of igneous rock. So, what are igneous rocks made from?

• Magma and lava

Igneous Rocks• If igneous rocks form from magma and lava,

where can igneous rocks form?

• On the surface = extrusive rock

• Below the surface = intrusive rock

Gneiss

Granite

Sandstone

• Quartzite

Shale

• Slate

Welcome to Science 1/4

Mighty Metamorphic RocksWhat does metamorphic mean?

Dynamic Change

What does it take to morph rock?

• When heat & pressure from

Deep inside Earth change

a rocks minerals, it becomes

a metamorphic rock.

How do rocks get deep inside Earth or how does heat come to the surface?

• Subduction

• Converging plates

• Rising magma

Directions: Each circle represents 1 of the 3 groups of rocks. In each circle write information about that group of rock. If groups of rock of something in common, write the info in the area where the circles overlap. You need to have at least 5 facts for each group of rock and at least 5 facts that are shared by the groups of rock.
