Explain Why Finding A Fossil Of A Fern In Antarctica Is Evidence For Continental Drift

Explain why finding a fossil of a fern in Antarctica is evidence for Continental Drift

 

Finding a fossil of a fern in Antartica is a great deal of evidence for continental drift because ferns do not grow there. The weather is too harsh for a fern to live in. Antarctica is considered a desert because it has very low levels of precipitation and the freshwater is scarce. If a fossil of fern is found there, then it means that Antarctica must have had a tropical or temperate climate as opposed to what it is now, and we know that temperate and tropical climates only occur if you are not in the polar regions. This is why scientists theorized that Antarctica has not really been in the polar region all this time. It must have moved from the lower latitudes before it gradually moved in the polar region.

First 25 term of arithmetic sequence 4,9,14,19,24   Answer: 4, 9, 14, 19, 24, 29, 34, 39, 44, 49, 54, 59, 64, 69, 74, 79, 84, 89, 94, 99, 104, 109, 114, 119, 124 Step-by-step explanation: The interval of each number is 5. Therefore, you just need to add 5 starting from 4. You can also see an obvious pattern that ends with 4 and 9, so you can use a shortcut method by following the pattern.

A Triangle Has Sides With Lengths 8x+6 And 5x-5. Find The Missing Side Length If The Triangle Has A Perimeter Of 7x+13.

a triangle has sides with lengths 8x+6 and 5x-5. find the missing side length if the triangle has a perimeter of 7x+13.   Answer: The third side is - 6x + 12. Step-by-step explanation: Perimeter of a triangle = Side₁ + Side₂ + Side₃ Side₃: y Given: Perimeter: 7x + 13 Side₁: 8x + 6 Side₂: 5x - 5 Side₃: y Equation: 7x + 13 = (8x + 6) + (5x - 5) + y 7x + 13 = (13x + 1) + y y = 7x + 13 - (13x + 1) y = 7x + 13 - 13x - 1 y = -6x + 12 The third side is - 6x + 12. Check: Perimeter = Side₁ + Side₂ + Side₃ 7x + 13 = (8x + 6) + (5x-5) + (-6x + 12) 7x + 13 = 8x + 6 + 5x - 5 - 6x + 12 7x + 13 = 7x + 13  (True)
