Question

B. Define the following terms:
1. Crust 2. Mante
3. Core
4. Nife
​

Answer 1

In geology, a crust is the outermost layer of a planet. The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The crust is underlain by the mantle. The upper part of the mantle is composed mostly of peridotite, a rock denser than rocks common in the overlying crust

Noun. mante f (plural mantes) mantis (any of various large insects of the order Mantodea)

core. [ kôr ] The central or innermost portion of the Earth, lying below the mantle and probably consisting of iron and nickel. It is divided into a liquid outer core, which begins at a depth of 2,898 km (1,800 mi), and a solid inner core, which begins at a depth of 4,983 km (3,090 mi).

nife. (naɪf; ˈnaɪfɪ) n. (Geological Science) the earth's core, thought to be composed of nickel and iron. [C20: from the chemical symbols Ni (nickel) and Fe (iron)]

Answer 2

Answer:

Explanation:

1) CRUST

• a crust is the outermost layer of a planet.

• The crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks.

• The crust is underlain by the mantle.
• Earth's crust occupies less than 1% of Earth's volume.
• The oceanic crust of the Earth is different from its continental crust.

2) MANTEL

• A mantle is a layer inside a planetary body

• They are bounded below by a core and above by a crust.

• Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body.
• Mantles are characteristic of planetary bodies that have undergone differentiation by density.
• All terrestrial planets (including Earth), a number of asteroids, and some planetary moons have mantles.

3) CORE

• The Earth's core is the part of Earth in the middle of our planet.
• It has a solid inner core and a liquid outer core.
• The temperature of the outer core ranges from 4400 °C in the outer regions to 6100 °C near the inner core.
• The outer core of the Earth is made of iron and nickel
• Whereas  the inner core of the Earth is an iron–nickel alloy

4) NiFe

• its meaning is : the earth's core, thought to be composed of nickel and iron
• the word originates from the chemical symbols Ni (nickel) and Fe (iron)
