A scientist claims that an intrusion of magma ( layer Y ) formed, scientists claim  Layer Y is larger in area than rock Layer Z.

All igneous rocks are created from magma, which is a naturally occurring substance that is molten or semi-molten. The Earth possesses magma beneath its surface, and other terrestrial planets and several naturally occurring satellites have also been confirmed to have magmatic activity.

Since molten rock behaves similarly to a thick, pasty material within the Earth, the word "magma" is derived from the Italian language. Another name for molten rock is lava, which is an Italian word that meaning to flow.

The upper mantle and the lower section of the Earth's crust are where magma first forms. The existence of magma is essential to comprehending the geology and morphology of the mantle because the majority of the mantle and crust are solid.

Thus, option C is correct.

Answer:

A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape.

Answer:

Liquid takes the shape of any container it is put in. The atoms that make up a liquid are spread out, and move fast, but not as fast as gas. Liquid is the stage between solid and gas, concerning the water stages. Usually, a liquid can turn into a solid or gas, if it's temperature or environment is changed.

Answer:

light is the result of electrons moving between defined energy levels in an atom called shells.

Explanation:

when something exited an atom like collision with another atom or a chemical reaction, an electron may absorb energy boosting it to a higher level shell.

Answer:

Less soil erosion

Explanation:

Due to the low amount of rainfall in this region, it is easier to say that the region compared to other ecoregion will suffer less soil erosion.

Erosion is usually the washing away of the top layer of the soil. Rainfall is one of the most important element that causes erosion. Surface runoff for an extended period of time can remove the topmost layer of the earth on which plant can grow. This starves the soil of its rich nutrients and minerals.

Answer: Flammability is a material's ability to burn in the presence of oxygen.

Explanation: Chemical properties can be observed only when the substance changes into one or more different substances through chemical reactions or transformations. One of the chemical properties is flammability.

Flammability is a material's ability to burn in the presence of oxygen.

Remember, oxygen doesn't burn. Precisely flammable substances obtain substances that burn. Oxygen remains an oxidizing agent, which means it supports the combustion process. Oxygen causes other objects to catch fire at low temperatures and burns hotter and faster. But oxygen itself does not burn. Consequently, if you at present deliver fuel and fire, adding oxygen will provide the fire.

Carbon dioxide is the result of combustion. An example can be seen in firewood in a fireplace. One of the chemical properties of carbon-based wood is having the ability to burn. Chemically the wood turns into carbon dioxide when it burns and leaves a residue of ash. Furthermore, this ash residue cannot be turned back into the wood. Chemical changes result in new substances.

Consider an example of a combustion reaction to methane gas:

Our balanced equation for methane combustion implies that every one CH₄ molecule reacts with two O₂ molecules. The product of combustion is one carbon dioxide molecule and two steam or water vapor molecules.

It is important to know the three different types of rocks because they contain clues about what the Earth was like in the past. Different rocks form under only certain conditions and can tell us something important about the past.

The study of rocks is very important to study the geography of rocks. To understand the Types of soil and rocks on the earth's surface.

There are three different types of rocks igneous, metamorphic and sedimentary rocks. Igneous rocks are formed from melted rock. Sedimentary rocks are formed from slit and animal skeletons.

Metamorphic rocks are formed by changing heat and pressure underground. Rock and mineral are important to understand the material, structure and system of the earth.

The study of rocks help in science and geography. Basalt is used in building rocks. Granite is used to form a monuments. Pumice is used as a scrubbing material. Slate is used for roofing material of roofs.

Therefore, The study of rocks is very important to study the geography of rocks. To understand the Types of soil and rocks on the earth's surface.

Explanation: a homogeneous mixture forms when two or more substances are combined to make something uniform. In this type of mixture, the components must be evenly distributed troughout. Only one state of matter can be present and you can see individual ingredients.

Answer: Na+ And F- & CI- and K+

The Na+ and F- and Cl- and K+ both can form ionic compound.

The ionic compound is the compound formed by the ions which is held together by ionic bond.

The bond formed by the oppositely charged ions through electrostatic force of attraction is called ionic bond.

The complete transfer of valence electron is takes place .

The ions should be oppositely charge .

The electronegativity difference between ions should be high.

The roman numeral is the metal's oxidation state used as the subscript on the nonmetal in the crisscross method.  Sometimes they are specified in the brackets with the name.

Oxidation state of an element is the number of electrons lost or gained in a chemical bonding. When atoms gains electrons they gets reduced to lower oxidation state whereas , when atoms loss electrons they oxidizes to higher oxidation state.

Metals are electropositive and and they form cations in bonding with non-metals. The charge of the metal is written as the subscript of the nonmetal and the charge of nonmetal will be the subscript of the metal.

Roman numerals are most significantly used in the case of transition metal compounds because, they are having variable oxidation states. Hence, to specify the  oxidation state of the transition metal, roman numerals are used.
