Question

Which of these statements best summarizes the section titled "Three-layer Cake"?

A. Earth is like a cake. The mantle is the cake. The core is the center of the cake. It is a very hot layer. The crust is a thin layer of icing on the cake.
B. Earth is made up of three layers. The top crust is the thinnest layer of Earth. The thickest layer, mantle, sits below the crust. Core is the hottest layer found at the center of Earth.
C. Earth looks like a cake. The mantle is the middle layer. It is also the thickest part. It makes up 84 layers out of 100 layers of Earth. The core is the hottest layer.
D. Earth has 100 layers. The top layer, crust, is only 30 miles thick, but the mantle is 1800 miles thick. So, mantle is the thickest layer of Earth. But most of the living things live on the crust.

Answer 1

Statement B is the correct summary, highlighting the three layers of Earth: the thin crust, the thick mantle underneath it, and the hottest inner core at the center.

Step-by-step explanation:

Among the statements provided, the one that best summarizes the section titled "Three-layer Cake" is: B. Earth is made up of three layers. The top crust is the thinnest layer of Earth. The thickest layer, mantle, sits below the crust. Core is the hottest layer found at the center of Earth.

The Earth's interior is indeed composed of the crust, mantle, and core. The crust is the outermost layer and varies in thickness from less than 5 km to more than 70 km. The mantle is approximately 2,900 km thick and has an ultramafic composition, making it the largest layer by volume. The core is mostly iron and nickel, with an inner solid part and an outer liquid part, and it is roughly 3,500 km thick. It is important to understand that the mantle is indeed the thickest layer, and the core is the hottest, due to its extreme pressures and temperatures.
