\frac{(2n+3)^{2}-(2n+1)^{2}}{6n+6} \\ \\ =\frac{(4n^{2}+12n+9)-(4n^{2}+4n+1)}{6n+6} \\ \\ =\frac{4n^{2}+12n+9-4n^{2}-4n-1}{6n+6} \\ \\ =\frac{8n+8}{6n+6} \\ \\ =\frac{4(2n+2)}{3(2n+2)} \\ \\ =\frac{4}{3} \\ \\ \therefore \boxed{a=4, b=3}

  1. The slowly increasing distance between South America and Africa is due to: a. <u>Seafloor Spreading</u>.
  2. Old Faithful Geyser at Yellowstone National Park in the United States of America acquires its energy from a: b. Hot Spot.
  3. Layered <u>sedimentary rock</u> exposed by erosion can be seen when looking at the Grand Canyon in the United States of America.

<h3>What is seafloor spreading?</h3>

<u>Seafloor spreading</u> can be defined as a process that involves the formation of new oceanic crust as a result of volcanic activities and an upwelling of molten magma at mid-ocean ridges, as well as a slowly increasing distance (outward movement) from the ridge.

The theory of <u>seafloor spreading</u> was established by Harry Hammond Hess and it can be used to explain in details the slowly increasing distance between South America and Africa which grows from the center.

<h3>What is a hot spot?</h3>

A <u>hot spot</u> refers to an area deep within Earth's mantle or under the rocky outermost layer of Earth, from which heat rises through convection and acquired as heat energy by a landform.

In the United States of America, you will see a layered <u>sedimentary rock</u> that is exposed by erosion when you view the Grand Canyon.

Furthermore, Australia is made up of relatively old and thick <u>continental crust</u>. Also, <u>subduction</u> causes the formation of extremely deep ocean Marianas Trench.
