its in the picture above

Answer 4

do u want newly found evidence or the years dont really matter

Answer 5

it dosent matter either way is fine ;)

And Salam :)

Answer 7

ok well to start off
Early development of plate tectonics:

In the 1900's, a German meteorologist by the name of Alfred Wegener was the first to present an argument supporting continental drift. He proposed that the continents were not stationary, but actually moving or drifting away from one another. His primary sources of evidence included the fit of the continents, glacial till deposits, and the apparent shifting of climatic belts over time. His colleagues at the time argued for polar wandering as an explanation of his data. These ideas were not well accepted until later scientists in the 1940's and 50's expanded on these ideas adding to them paleomagnetism, convection currents and sea floor spreading. With all this new evidence, plate tectonic theory became an accepted idea .

Answer 8

Wegener noticed that the continents seemed to fit together, not at the continuously changing shoreline, but at the edge to their continental shelves. He derived this hypothesis from the observation that the continents in the southern hemisphere exhibit an identical pattern of rock and fossils known as the "Gondwana sequence".

Answer 9

A second idea supporting movement of the continents was the glacial till deposits in the southern hemisphere. With the continents in their present positions, the till deposits indicate erratic glacier motion.

Answer 10

Okay thats perfect and I understand it can we others. :)

Answer 11

ur welcome , is that good enough or do u need more

Answer 12

ok give me a minute

Answer 13

im not really sure , but this is all i can really think of for this one :
A volcanic explosion can cause considerable short term damage to the biosphere, not only locally due to blast but even globally due to volcanic particles obscuring sunlight, and causing cold and loss of plant productivity. In the long run however, volcanic eruptions enrich the biosphere by producing rich volcanic soil

Answer 14

Can we multiple choice ones?

Answer 15

what do u mean is it a multiple chocie question
?????

Answer 16

ok sure
let me take a look

Answer 17

for question 15 a tsunami is A tsunami is a series of large waves generated by an abrupt movement on the ocean floor that can result from an earthquake, an underwater landslide, a volcanic eruption or - very rarely - a large meteorite strike.

so you would just see which answer fits with the description

Answer 18
