Answer:

Scientists believe that plate tectonics is an example of an internal force that changes the Earth’s crust.

Plate tectonics is a theory that describes the motion of seven large plates, and many other smaller plates of the Earth's lithosphere. When they collide they can make mountains or we can feel their motion as earthquakes. Their motion is responsible for the continental shift and it made our continents look the way they look today.

A metal sphere of radius 9 is melted and transformed into three identical spheres. b What is the ratio of the area of one of the

Romashka [77]

Answer:

25:52 the ratio of the area of one of these spheres to the area of the original sphere.

Explanation:

Radius of metal sphere ,R= 9

Volume of metallic sphere, V = $\frac{4}{3}\pi R^3$

Radius of small metal sphere = r

Volume of small sphere made form metal sphere = v

$v=\frac{4}{3}\pi r^3$

Volume of metallic sphere = Total volume of all 3 small spheres

V = 3v

$\frac{4}{3}\p R^3=3\times \frac{4}{3}\p r^3$

$R=\sqrt[3]{3}r$

Area of sphere = $4\pi (radius)^2$

Area of metal sphere = $A=4\pi R^2$

Area of small metal sphere = $A'=4\pi r^2$

The ratio of the area of small spheres to the area of the original sphere:

$\frac{A'}{A}=\frac{4\pi r^2}{4\pi R^2}=\frac{r^2}{R^2}$

$=\frac{r^2}{(\sqrt[3]{3}r)^2}=\frac{1}{(\sqrt[3]{3})^2}=\frac{1}{2.08}=\frac{25}{52}$

25:52 the ratio of the area of one of these spheres to the area of the original sphere.
