continental drift/sea floor spreading

Identify 4 evidences the helped prove the continents where moving and explain each one.

the evidence of all the continents moved over time is continental drift

1.fossils - they have found the same fossils on different continents

2.marks - the marks where they split and moved made scratches

3.coal - coal has been found on different continents from when they where together

4.shapes - the contents look like a puzzle that could be put together

 Good work

Seafloor Spreading-Explain it. - how the sea floor spreads involving aging of rock and magnetic reversals over time.

Identify 2 evidences that helped prove the sea floor was growing and explain each one.

1.ageing of rock - the same rocks show the difference of the age to show  sea floor spreading

2.magnetic reversals - it shows how the reversal made the continents spread apart and show sea floor spreading. Nice work

Continental drift/ Seafloor spreading

Continental drift-Explain it.
Continental Drift mean "all land".Continents have slowed moved to their cur what? 


Identify 4 evidences the helped prove the continents where moving and explain each one. Very good

1.  Oil and Coal: separated they started in the same spot 
2. Fossils: All of the organisms were all together then got separated 
3. Glaciers: They left glacial striations 
4. Rock Formation: geological structures 

Seafloor Spreading-Explain it.

Hess’s theory that new sea floor is formed when magma is forced upward toward the surface at a mid- ocean ridge. Very good

Identify 2 evidences that helped prove the sea floor was growing and explain each one.

1. Magnetic Reversals: the metal particles in the lava pointed toward the polarity at that time.

2. Radiometric Dating: researchers took rock samples and aged them.

Seafloor Spreading-Explain it.

Identify 2 evidences that helped prove the sea floor was growing and explain each one.

1. Fossils

2. Climate

The continents were all one peice. Over the years the continents are sperating through out the years. Thats why all of he continents are no together anymore. That is why all of the fossils that are found on different countries are the same. This happened when the animals scrossed over to different continents and never crossed back over before they sperated. 

The fossils that are found on different continents are becuase of the continental drift. If the continents we have not sperated all of the animals and the fossils would have been found on the same continent. But since they seperated that is why the fossils are not on the same continent.

Evidence of evolution

cross breading plants is when farmers breaded to plants to get a better one.

 

some evidence is like the animals in the desert that changed to live there

                   plant fosles 

Evidence of Evolution

List and explain 3 examples of evidence of evolution. Support your answers with at least one picture


1. Fossils, scientist study fossils and compare them with other animals. Some animals do not become a fossil so the fossil record is not complete.

  

2. (Homologous structures) Between billions to millions to thousands of years animals change a lot in that period of time. Scientist study and compare them so can see what they were like.

3. DNA- It is cool to find a DNA sample of your own kind. An example is like when you give blood it has parts of your DNA in it.

Evidence of Evolution By: Dawson J

     There are multiple examples of evidence of evolution but there are only a three that really stick out. One example is fossils. Fossils can provide evidence of evolution because they show the different stages of evolution something went through. Homologous structures is another example of evolution because it shows the similarities between the arms of multiple species. Another is vestigial structures such as the appendix, and the pelvis in a whale.
