Tectonic plates are large segments of Earth’s mist that move slowly. Suppose one such plate has an average speed of 4.0 cm/yr. (a) What distance does it move in 1.0 s at this speed? (b) What is its speed in kilometers pet million years?
From Hawaii to the bend in the Hawaiian-Emperor chain is about 4000 km. Use the speed of Pacific plate motion given in Problem 7 to estimate how long ago the direction of plate motion changed. (Note: It may not be a coincidence that the San Andreas fault became active in what is now Southern California at about the same time.) 7.

Question 4 Every year over 105 km2 of forest area is lost to human activity. This is about one seventh the area of Texas as shown on the map in red. If our planet has 19.4 x 106 km2 of forest area, how long will it to take to lose it all? Hint: divide the total forest area by the given rate of deforestation. Calculations: Answer: Question 5 The Great Pacific Garbage Patch is an area of plastic waste twice the size of Texas in the Pacific Ocean. It is estimated there are 1.8 x 1012 pieces of plastic in this patch. If the world’s population is 8 x 109, how many pieces of plastic are there per person? Hint: divide the total pieces of plastic by the number of people. Calculations: Answer:
