Answer: Sea-floor spreading — In the early 1960s, Princeton geologist Harry Hess proposed the hypothesis of sea-floor spreading, in which basaltic magma from the mantle rises to create new ocean floor at mid-ocean ridges. ... A test of the hypothesis of sea-floor spreading was provided by studies of the Earth's magnetism.
It is called Globalization
Answer: the answer is A
Explanation: i just took the unit test got a 100 pls give brainiest
Answer for first picture:
#1 = 43 degrees #2= 38 degrees
#3= 27 degrees #4= 45 degrees
Explanation for first picture:
All the angles are right angles. This means they all will equal 90 degrees! so if you take 90 degrees and subtract the one known angle you will have your answer! :)
Answer for 2nd picture:
#1 = X= 70 Y= 110
#2 = X= 102 Z= 102
#3 = X= 83 Y= 194
#4 = Y= 37 Z= 143
Explanation for second picture:
When you have angles like these the total will equal 360 degrees! look at the first pic, it shows 110 degrees, you also know that the angle across of it is equal to it. so together it equals 220 now subtract 360 - 220. you get 140. since you have two angles to figure out, you divide 140 into two. 140 / 2 = 70 degrees! you do the same steps for the rest of the problems!
( i am sorry for the bad explaining!)
Here is the answer. The approximate percentage of land on Earth that is devoted to farming or agricultural land is 37% and one third of this area, or 11% of the Earth's total land is allocated and used for crops. Hope this is the answer that you are looking for.
