Question of the Day

• This is a 2 part question.
• 1. What type of rock makes up 90 of Earths
  crust?
• Igneous rock
• If igneous rock makes up 90 of Earths crust how
  did other rocks form to make the remaining 10 of
  Earths crust?
• Weathering erosion helped make new types of
  rock as well as processes like EQs and
  subduction.

Igneous Rocks
What do you know?
4
Igneous Rocks

• Igneous come from the latin word ignis, meaning
  fire
• 90 of Earths crust is made of igneous rock.
  So, what are igneous rocks made from?
• Magma and lava

5
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

6
Granite
Gneiss
7
Sandstone

• Quartzite

8
Shale

• Slate

• 4. Metamorphic Rocks
• 5. HW Assignment

10
Mighty Metamorphic Rocks

• What does metamorphic mean?
• Dynamic Change

11
What does it take to morph rock?

• When heat pressure from
• Deep inside Earth change
• a rocks minerals, it becomes
• a metamorphic rock.

12
How do rocks get deep inside Earth or how does
heat come to the surface?

• Subduction
• Converging plates
• Rising magma

Venn Diagram
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.
