C. ShortAnswerTypeQuestions.

1. Why is the Earth hot from inside? How can you show it?

2. What do you know about the structure of the Earth? Name its layers.

3. What is lithosphere? How thick is it and what is it made up of?

4. What are minerals?

5. Why are igneous rocks called primary rocks?​

Answer 1

Explanation:

1,There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements

2,The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface.

3,Oceanic lithosphere is typically about 50-100 km thick (but beneath the mid-ocean ridges is no thicker than the crust). The continental lithosphere is thicker (about 150 km). It consists of about 50 km of crust and 100 km or more of the uppermost mantle.

4,A nutritionist uses the word mineral when referring to the many inorganic substances that organisms need to grow, repair tissue, metabolize, and carry out other body processes. Mineral nutrients for the human body include: iron, calcium, copper, sulfur, phosphorus, magnesium and many others.

5,igneous rocks are formed from magma and begin the rock cycle, they are called primary rocks.

Answer 2

Answer:

1. THE EARTH IS HOT BELOW THE GROUND BECAUSE CRUST , MANTLE CORE, INNER CORE, AND THE EARTH HAS RADIO ACTIVE ELEMENTS WHICH CAUSES HEAT AND HEAT IS MEASURED BY How do we know the temperature? The answer is that we really don't--at least not with great certainty or precision.
2. WE LIVE ON THE CRUST AND THERE ARE 3 LAYERS WHICH ARE VERY HOT TO SURVIVE AND WE KNOW THAT THE LAYERS ARE CRUST, MANTLE ,INNER CORE,OUTER CORE
3. The lithosphere is the solid shell of a rocky planet called earth. That means the crust and the upper part of the mantle which is joined to the crustOceanic lithosphere is typically about 50-100 km thick (but beneath the mid-ocean ridges is no thicker than the crust). The continental lithosphere is thicker (about 150 km). It consists of about 50 km of crust and 100 km or more of the uppermost mantle. it is made up ofThe oceanic lithosphere consists mainly of mafic crust and ultramafic mantle and is denser than the continental lithosphere, for which the mantle is associated with a crust made of felsic rocks
4. In geology and mineralogy, a mineral or mineral species is, broadly speaking, a solid chemical compound with a fairly well-defined chemical composition and a specific crystal structure, that occurs naturally in pure form. it can be in liquid form or solid form
5. As igneous rocks are formed from magma and begin the rock cycle, they are called primary rocks.
7. Explanation:
8. Igneous rocks are created from the cooling of molten magma/lava. All other rocks are derived from them, which is why you will also find them referred to as parent rocks on occasion
