There are three types of rocks on Earth. Each rock type forms in a different way. Igneous rocks were the first rocks on Earth. T

hey form from molten rock. Molten rock is rock that has turned to liquid because of extreme heat. Lava is the name for the molten rock that erupts from volcanoes. When molten rock is below the Earth’s surface, it’s called magma. When molten rock—either lava or magma—cools, it hardens into a solid. This forms igneous rocks. Some examples of igneous rocks are granite, obsidian and basalt. Much of Hawaii’s coast is covered in basalt. Waves break the basalt down over time, creating the black sand of some Hawaiian beaches.
Which of the following is true about lava and magma?
A. Lava and magma are both types of molten rock.
B. Magma uses waves to break down lava over time.
C. When magma cools and hardens it becomes lava.
D. Magma is called lava when it’s below the Earth’s surface.

Bess [88]

Answer:

each rotation of the smaller wheel will show 84.382-75.3982=8.9838 inches more than the actual distance

Explanation:

d = Diameter of the wheel

The distance traveled in one rotation of the wheel is the circumference of the wheel

\pi d=\pi\times 27\\ =84.823\ inch

When diameter is 24 inches

\pi d=\pi\times 24\\ =75.3982\ inch

Therefore, each rotation of the smaller wheel will show 84.382-75.3982=8.9838 inches more than the actual distance
