APES 12/1 and 12/2

• No Warm-Up today…or ever again • Please take out Module 24 and your plate

tectonics map• Pick up your folder• If you have a soil sample, label it and put it on

the lab station by the fume hood.

Folder Grading

1. 2 current events (both stamped): 20 pts2. Wolf FRQ: 5 pts.3. Biome Spreadsheet: 5 pts.

- Graded (mostly!) on completion since you correct your FRQs in class

Plate Tectonics Map Check-In

• Compare work with your table partners • Put it in your folder and file your folder in the

black crate• On the way back, get a computer and a

textbook

Module 24 Multiple Choice1. A – earth’s core is mostly Iron and Nickel2. C- subduction is one plate passing under another3. B- Hawaii was formed at a hot spot (a weakness

in the pacific ocean plate where magma was allowed to leak out)

4. B- see work on the whiteboard5. E- metamorphic rock is formed at high

temp/pressure6. C- earthquakes occur mostly at transform

boundaries

Plate Tectonics Notes!

• See 11/30 PPT

Plate Tectonics FRQ

• Answer on the back• You may use notes• Use complete sentences always!• Pay attention to verbs- describe, identify,

explain, etc.• We will score it in 20 minutes or so.

The Rock CycleHow does the

lithosphere form?

Types of rock

Igneous MetamorphicSedimentary

Pools of magma cool down slowly in the crust to form igneous rocks.

Igneous rocks are crystalline and hard to break.

Magma is pushed to the surface by volcanoes..

Larger crystals are obtained through slow cooling – such as granite.

Smaller crystals form through fast cooling – such as pumice.

- Igneous Rocks on the surface of the earth are weathered by wind and water to form smaller particles. - Wind, water and/or ice transport these particles to floodplains and the sea by erosion. - The pressure of many layers changes the bottom layers into sediments.

Sedimentary Rock

• Forms from sediment particles that are deposited by water, wind or ice.

• Formed under great pressure – no heat is involved.

• Properties:– Found in layers– Often contains fossils

Hot magma heats the surrounding rock and the chemical structure changes to form metamorphic rock.

Eventually the metamorphic rock melts down and becomes magma again!

Metamorphic Rock

• Rock that started as igneous or sedimentary.

• Forms due to immense heat and/or pressure of the earth’s crust.

• Properties:– Crystalline – Compressed

structure

Introduction to Soil

11. Draw a diagram showing the major layers of soil. List the major characteristics next to each layer. Which is “topsoil”?

Research this now with your group!

Prepare for Soil Lab

• Lay your soil sample out to dry on a labeled paper towel.

• No sample? Dig down to the B horizon at home and bring it in next time!

• Also due next time:Rest of Ch. 8 Reading Assignment!
