Відповідь:Let's evaluate each statement:

"The core is divided into the inner core (which is fluid) and the outer core (which is solid)."

Correction: This statement is false. The inner core of the Earth is actually solid, primarily composed of iron and nickel. The outer core, on the other hand, is fluid and molten.

"The mantle is thicker than the outer core."

Correction: This statement is true. The mantle is indeed thicker than the outer core. The mantle is a semi-solid layer located between the crust and the outer core, and it accounts for a significant portion of the Earth's volume.

"The crust makes up over 80% of the volume of the Earth."

Correction: This statement is false. The crust is the Earth's outermost layer, and it represents only a very small fraction of the Earth's total volume, estimated to be less than 1% of the planet's volume.

"Temperatures in the mantle are so high that its rocks are completely molten."

Correction: This statement is false. While the temperatures in the mantle are high, they are not high enough to completely melt the rocks. The mantle consists of solid rock that can flow over long periods of time, but it is not entirely molten. The partial melting of some rocks in the mantle can create magma, which can then rise to the surface in volcanic activity.

So, statements 1 and 3 are false, while statements 2 and 4 are corrected.
