What are facts about Pangea?
Pangea was a supercontinent that existed about 335 to 175 million years ago during the late Paleozoic and early Mesozoic eras. It was surrounded by a single large ocean called Panthalassa and eventually broke apart due to tectonic plate movements, leading to the formation of the continents we have today. The theory of Pangea was proposed by Alfred Wegener in 1912, based on the fit of the continents, matching rock formations, and fossil evidence.
How was fossil evidence used to reconstruct Pangea?
The intersection of a common fossil on two different landmasses' borders allowed scientists to reconstruct Pangaea.
Why coal is fossil fuel?
it is made from once living things when the pangea on the earth moved away
To be useful as an index fossil fuel spices must have existed for how long?
To be useful as an index fossil fuel, spices must have existed for about 1000 years.
What word refers to traces of an organism that existed in the past?
A fossil is a trace of an organism that lived long ago.
What is a tropites fossil?
A tropites fossil is a fossil of a tropites. A tropites is a genus of coiled ammonite. They only existed for about 20 million years, which makes it a good index fossil.
What fossil proof was there animal existed for saber-toothed tiger?
not much
Why can you not find every type of organism that ever existed as a fossil?
because it is hard to solve the fossil and the organism it is
Why do we only have fossils of a fraction of things that have existed on earth?
Many environments are not suitable for fossil formation.
How could the duckbill dinosaur tooth fossil lead scientists to believe that plants also existed in Antarctica?
Because hadrosaurs could not have survived without plants, their presence in Antarctica proves that plants existed there. Additionally, fossil plants have been found in Antarctica.
What is thought to be the cause of the global climates change?
Mankind's activity in burning fossil fuels to make Greenhouse gases.
What 4 main types of evidence support continental drift theory?
The four main types of evidence supporting the continental drift theory are: Fossil evidence showing similar plant and animal species existed on continents that are now widely separated. Geological evidence such as matching rock formations and mountain chains across different continents. Paleoclimatic evidence, where past climate data from different continents align when the continents are reconstructed as a single landmass. Seafloor spreading and magnetic stripes on the ocean floor supporting the movement of continents.
