What fossils did Alfred wegener find and where?
The fossils of animals were found the three different continents, but no animal could've swam that far across the salt water, so there had to be another way. Also, the plant fossil glossopteris was discovered in Antarctica, where no plants could live.
Why are isotherms generally parallel across the US?
Isotherms connect points of equal temperature on a weather map. The lines of isotherms naturally run parallel to each other. Their spacing indicates temperature variance.
How do fossils support the theory that the continents were once joined together?
The Continental drift theory posits that the shoreline of many continents were at one time interlocked. Through tectonic movement and axis shift, the continents have drifted apart as is evidenced by similar animal fossils on differing continents.
What is Wegeners hypothesis?
Wegener hypothesized that, on earth, there was only one continent called Pangea, but it split into the continents we have now.Improved Another Answer:Wegener's hypothesis was that long 225 million years ago, there was a supercontinent called Pangaea (All the continents were all together).Wegener saw that South America and Africa looked like they could fit together like puzzle pieces. He then found that there were fossils of animals in a warm climate and it was also in a very cold climate. He thought, "How could that be? The animal couldn't have lived in two different kinds of climates and how could it have swam across the sea?!"
How are the trends in the periodic table helpful in identifying an element?
The periodic trends that arise from the arrangement of the periodic table provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or period and the periodic nature of the elements.

What continents do you travel across from Africa to Antarctica?
None. You would travel across the Southern Ocean to get from Africa to Antarctica.
What are the average temperature trends for the last 5 years?
5 years is far too short a time for any indicative trends in such things.
What is the most important in determining the periodic trends across a period?
increasing number of electrons
