Day 162 Geology 6 x 6

May 20, 2012 Day 162
Math: 2 pages
LA Book: 1 page
Library Visit: chose books about Rocks & Minerals, America 1870-1915, and Joshua Chamberlain

Geology: Geology of the Eastern Coast by Cynthia Light Brown and Kathleen Brow
Amazon link to book

pages 8-17
6 Vocabulary
1. Current: A constantly moving mass of liquid
2. Divergent boundary: where two plates are moving in opposite directions
3. Rifting: when the lithosphere splits apart
4. Metamorphic rock: rock that has been transformed by heat or pressure or both into new rock, while staying solid
5. Subduction: when one tectonic plates slides under another tectonic plate
6. Transform boundary: where two plates slide against each other

6 Sentences
1. The heat in the asthenosphere causes the magma in a huge rotating current called convection cells.
2. Divergent Plate boundaries happen when the magma beneath is pushing upward.
3. Divergent plate boundaries cause rifting; the hot liquid comes out and forms in to a new rock.
4. Just like metamorphic rock is transformed by heat and pressure, some rocks are transformed by the ocean and become smoother.
5. When oceanic plates and continental plates collide it forms a volcano, since the oceanic plate is thinner than the continental it is subduction.
6. I thought it was interesting that there is a transform plate boundary that runs from New York to Alabama; we probably drove near it.

6 Facts/ Details
1. The oldest rocks in the U.S are in Minnesota and Michigan; they are between 3.5 and 3.7 billion years old.
2. The oldest rocks on Earth are in Canada, they are 4 billion years old
3. A good synonym to explain how tectonic plates act is like a giant conveyor belt
4. When the Appalachian Mountains formed a long time ago, they were probably as high as the Himalayas are today; since then wind water and ice have eroded them
5. The Atlantic Ocean spreads apart about ½ inch every year
6.  During the Ice Age, there were glaciers in New York, Pennsylvania and New Jersey; As the Earth warmed they became into lakes and rivers

6 Questions
1. What does elevation measure? A: height above the sea level
2. How much wider now is the Atlantic Ocean than when Columbus crossed it and why? A: 33 feet
3. How are plate tectonics like a giant conveyor belt? A: because they are used to move people or things across a long space,
4. what is an orogeny? (page 13) A: The process of continents colliding together
5. What was happening on the East Coast 240 million years ago when dinosaurs were roaming? A: Pangaea was rifting apart
6. List and describe the 3 main types of rock:

Sedimentary rock: formed when small rocks are pushed tightly together

Igneous Rocks: rocks formed from molten rock that has entered the air and become cool.

Metamorphic rocks: rocks formed from heat and pressure

6 things you learned/ observed about Geology in cave to Ruby Fall
1.  The rock formations that we saw took a long time to form because it takes a year just to “grow” about an inch
2. The rock formations felt smooth and sort of slimy
3. The rocks in the cave were creating some of the puddles and pools that were in the cave
4. Some of the rocks had like, ripples in them, the ripples were created by the wind and how it has to funnel because of the other rocks.
5. Some of the rocks were formed to look like animals such as the turtle, the donkey, and the fish formations; they were created by dripping water and wind which kind of sculpts them.
6. All of the rocks in the cave was limestone

6 Pictures of cool rocks you find around the gardens and ponds--take your camera and go outside!
