When did Alfred Wegener discover the theory of plate tectonics?
In 1910 Continental Drift was toyed around with by a man known as Alfred Wegner. He actually went through with the idea in 1912. The way He really discovered it was by noticing on a map how Africa and South America could almost completely fit together. So he started putting all the Continents back together and it created one giant land mass called Pangea that existed about 500 million years ago
Why would you expect to see similar rock structures on two landmasses that were once connected?
Because continental drift occurred at that time but as time passed the continents again drift apart but keeping the fossils of the plant or animal still in that one continent, therefore having the fossil be separated.
What are the strengths and weaknesses of continental drift theory?
Strengths are the fact that the continents all fit like a puzzle. Also, there are many evidences that support the theory. One, coal deposits (usually found in tropical climates) were found in the North Pole. Alfred Wegener concluded that NP could have been located near the equator when it was part of Pangaea. Two, fossils of the same species were found in South America and South Africa. These organisms could not have travelled over the vast seas of present day. The only way to explain it was that these two pieces of land were connected. Three, there were signs of glaciation at South America and Africa and the patterns of the striae left behind are similar in both continents, leading Alfred to believe they were connected. Weakness was that people could not explain the forces or mechanism that caused these continents to move such great distances, until the 1960s, when plate tectonics was introduced. I can't find/think of any more weaknesses but I hope this has helped brother. Peace.
What are two structures you would find at a passive continental margin?
There are two structures that would be found at a passive continental margin. These structures are continental shelves and continental slopes.
What is one structure you would find at an active continental margin that you would not find at a passive coninental margin?
On an active continental margin, you would be likely to find an active ocean trench. This structure would generally not occur at a passive continental margin.

Wegener's continental drift hypothesis was weakened because a viable mechanism for moving the continents was lacking?
Yes, they could not find a reason that would cause the movements of the continents. Now, scientists have discovered that the continents don't drift, but rather they are carried by tectonic plates.
What key evidence did Alfred Wegener use to support his hypothesis of continental drift?
Alfred Wegener's fully developed theory of continental drift attempted to point out evidences that the continents were once joined into a single continent he called Pangea. Wegener's theory hypothesized that the continents were able to push through the rock of the seafloor to their present positions. As evidence, he noted, as had others before him, of the geographic correlation in coastline perimeters of South America and Africa. This was the feature that led Wegener to investigate for other evidences. His investigations revealed that mountain ranges in South America and Africa, and strata and composition of coal fields in Europe and North America matched or lined up. Additionally, matching reptilian fossils were found on either side of the ocean, indicating that the continents were once joined together. Although he was unable to find a mechanism for his proposed continental drift theory, he also observed that the more shallow an ocean, the younger its geologic age. It wasn't until the 1950's and 1960's, with the discovery of the Mid-Atlantic Ridge, and other sea floor mapping discoveries that Wegener's hypothesis started to become more accepted. The newer science of plate tectonics owes much to Wegener's scientific groundwork.

Where can a person find a sentence for the word Continental Drift?
Due to CONTINENTAL DRIFT, Europe is not in the same general area it was in 1 billion years ago
What are two historical figures in the process of mantle convection and plate movement?
1) In 1912, a German meteorologist named Alfred Wegener began lecturing and writing scientific papers about continental drift. Wegener's idea was that the continents had once been joined together in a single "supercontinent," which he called Pangaea (pronounced Pan-JEE-ah), meaning "all lands". He suggested that Pangaea had split into fragments like pieces of ice floating on a pond and that the continental fragments had slowly drifted to their present locations. 2) I could not find a second person in my text (sorry)

What was Alfred Wegener's first presented idea of continental drift?
In 1915 the first edition of The Origin of Continents and Oceans, a book outlining the Continental Drift theory of Alfred Lothar Wegener, a German meterologist, was published; expanded editions were published in 1920, 1922, and 1929. About 300 million years ago, claimed Wegener, the continents had formed a single mass, called Pangaea (from the Greek for "all the Earth"). Pangaea had split, and its pieces had been moving away from each other ever since. Wegener was not the first to suggest that the continents had once been connected, but he was the first to present extensive evidence from several fields. He was subsequently proved right, although he was wrong in one respect; the continents don't drift on their own, they move as part of much larger "plates" of the Earth's surface, much of which is ocean floor.
What websites could you find essays for continental drift?
You have to write the essay and not someone do it for you.
How can fossils help show that continental drift happened?
It can help show that continental drift happened, if you find the same fossils on different continents. This would mean that the continents had to be close together if the fossils are found on land.
