1. We took a Bunson Heater and put a beaker with water in it and heater the water. Then we waited until we saw some bubbles and then put some food coloring in and watching it spread through the whole beaker.
2. The colorling spread through the whole beaker and then turend that color. Then we put some styrophome and it melted.
3. We did this so we under stood what plate tectonics were and sea floor spreading.

bunson burners and beakers
today we put a beaker on a bunson burner and heated up the water then we put food coloring in it to represent the mantle i saw the food coloring getting mixed up alot and (turning colors) we did this to to show what the bottom of the earth is like

seafloor spreading/continantal drift
Identify 4 evidences the helped prove the continents where moving and explain each one.
1. climate change
2. fossils
3. mountain ranges
4. coal
Seafloor Spreading-Explain it.
Identify 2 evidences that helped prove the sea floor was growing and explain each one.
1. the mid-alantic ridge- new seafloor is coming from it and moving away from it
2. subduction zones- is where it takes the seafloor and recycles it

Continental Drift Spreading
Continental drift-Explain it.
Identify 4 evidences the helped prove the continents where moving and explain each one.
1.Mesosaurus: lived on both continents when they where joined
2.glossopteris: its been found in Africa, Australia, India, South America
3.climate clues: South America, Africa, India, and Australia
4.rock clues: Greenland and Western Europe
Seafloor Spreading-Explain it.
Identify 2 evidences that helped prove the sea floor was growing and explain each one.
1.divergent boundaries
2.magnetic alignment of rocks in alternating strips

seafloor spreading/continental drift
Continental drift-Explain it. The moving of the continents over long periods of times. Very Good!
Identify 4 evidences the helped prove the continents where moving and explain each one.
1.fossil that were found in other countries that are the exact same
2. plants in ice bergs
3. mountains that are the same in two different continents
4. shapes of the continents that look like puzzle pieces that could connect
Seafloor Spreading-Explain it.
Identify 2 evidences that helped prove the sea floor was growing and explain each one.
1. the floor is older in some places and newer in other places
2. magma sprouts out and makes new flooring
Magnetic Reversals

Continental Drift/Seafloor Spreading
Continental drift/Seafloor Spreading.
Continental drift-Explain it. The gradual movement of the continents across the earth's surface through geological time.
Identify 4 evidences the helped prove the continents where moving and explain each one.
1. Puzzle pieces
2. Tropical glaciers scratches
1. Puzzle pieces
2. Tropical glaciers scratches
3. Mountain Minerals
4. Similar Fossils
Seafloor Spreading-Explain it. The formation of new areas of oceanic crust, which occurs through the upwelling of magma at mid-ocean ridges and its subsequent outward movement on either side.

Identify 2 evidences that helped prove the sea floor was growing and explain each one.
1. First, samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid- ocean ridge is approached, and the sediment cover is thinner near the ridge.

2. Magnetic Reversals is the 2nd proof. A much better fit between the rifted continents is apparent when the shape of the continental slop is used instead of the continent's shoreline. Detailed mapping of distinctive rock units that extend out to sea along the South American and African coasts and North American and British coasts has shown that they would converge perfectly if the continents could be fitted together.
sea floor
continental drift is when the continentals drift apart and make now land. it was all one land mass
Identify 4 evidences the helped prove the continents where moving and explain each one.
1. Glacier scratch in the land forest
2. foils or on to different places
3. mounts in different places that are made in the same time
4. they look like puzzles
Seafloor Spreading is when magma comes up and cools and makes now land
Identify 2 evidences that helped prove the sea floor was growing and explain each one.
1. sonar Nope
2. MT's that you can see Nope..what are MT's?
