How-old-is-our-planet-earth-Geography-Discussion-Help-2

Can someone help me answer the below questions:

1.) How old is our planet earth and what is the significance of knowing this information. Can knowing the age of the Earth help us better understand the processes that shape its surface?

Try to relate these processes to the “Law of Uniformitarianism.” Use internet resources to define what the law entails.

2.)When Alfred Wegener argued early last century that all continents had once been connected but had cracked and moved apart, he had little to support his hypothesis besides the shape of the continents. Today, much evidence supports the hypothesis of continental drift, not the least of which is an accurate measurement of increasing or decreasing distances between fixed points on various plates. Not only are horizontal movements on the order of centimeters per year measurable with modern equipment, but the much slower lifting of mountains is also measured with greater accuracy.

What modern equipment is capable of making such fine measurements on shifting surfaces, and when was it developed? When a plate is said to move northeast at the rate of one inch per year, to what is the movement relative to? Besides these readings, what other evidence have scientists found that all the Earth’s landmasses were once connected? And which mountain ranges are still being formed, which ones are eroding? What kind of a fault is associated with the Great East African Rift Valley?

3.) Tornadoes are violent and quite unpredictable, while hurricanes and typhons are large and slow-moving but more destructive. Use library and Internet resources to find the similarities and differences between these types of storms. Please answer at least three of the following five questions: Make sure that you indicate which question you are answering so your classmates can follow your discussions.

 1)Where would you most likely find these three storm types, and what conditions are favorable for their formation?

2) In the USA, what regions are most at risk, and why?

3) On what basis is the intensity of tornadoes or hurricanes rated, and how is their strength actually measured?

4) When and where were the most intense cases of each?

5) How bad are losses of life and property, and what are the most common causes of such loss – fire? winds? flooding?

How does one protect self and property from either type of storm? Consider reading accounts of specific storms; what might one expect to happen in the path of a severe hurricane or a severe tornado?

4.) There are three types of plate boundaries:

•divergent,

•convergent, and

•transform. 

Explain each plate boundary type and give specific examples of places on Earth where these types of plate boundaries can be observed.
