A.
Asia Minor
B.
Palestine
C.
Cyprus
D.
the Sinai Peninsula
Answer:
B. Palestine
Explanation:
b. heat
c.extreme pressure
d. weathering
The option B is correct.
The primary agent of contact metamorphism is heat.
Further Explanation:
Contact Metamorphism:When magma is injected towards the surrounding rock, the changes that take place are referred as Contact Metamorphism.
The greater changes take place when the magma touches rock because the temperatures roses as the distance between the boundary and the magma decreases and reaches the highest when it touches the rock or the boundary. The igneous rocks that are formed around from the cooling of the magma arereferred as a metamorphosed zone or a contact metamorphism aureole.The change that occurs is due to chemically active fluids, heat and pressure.
The ore minerals are formed by the process of metasomatism near or at the contact zone. The aureoles show different degrees of metamorphism spreading from the contact area to metamorphosed rock.Therefore,the primary agent of contact metamorphism is heat.
Therefore, the option B is correct.

The primary agent of contact metamorphism is:
(B) Heat
Contact metamorphic rocks are formed due to the influence of magma intrusion at very high temperatures. The temperature is very high because it is located close to the magma. The word metamorphic was taken from the Greek words meta and morph. Meta means change, and morph means form. So, we can conclude that metamorphism is the process of changing rock form.
The primary agent of contact metamorphism is the heat. High temperatures come from magmas injected in the surrounding solid rock. Marble is one of the examples of contact metamorphic process. It is created from limestone that has been subjected to heat.
Besides the contact metamorphism, there are two other processes such as dynamo metamorphism, and pneumatolytic metamorphism. Dynamo metamorphism is influenced by high pressure, but pneumatolytic metamorphism is influenced by gases and chemicals.

The global meteoric water line (GMWL) is a linear relationship that describes the isotopic composition of precipitation (meteoric water) in various regions of the world. It is represented by the equation:
δD = 8 * δ18O + 10
In this equation, δD represents the deuterium excess, and δ18O represents the isotopic composition of oxygen-18 in meteoric water.
Warm and Moist Areas: In warm and moist regions, such as tropical rainforests, you typically find precipitation falling on the lower-left end of the GMWL because both δD and δ18O values are relatively high. The warm temperatures contribute to higher values.
Dry, Colder Areas: Dry and colder regions, like polar areas or high mountainous regions, tend to have precipitation falling on the upper-right end of the GMWL, as both δD and δ18O values are relatively low. The cold temperatures and lower humidity contribute to these lower values.
The GMWL helps scientists understand the sources and processes influencing the isotopic composition of meteoric water in different climatic regions.

Our Sun is considered average because its temperature and absolute magnitude place it in the middle of the main sequence range of the H-R diagram. Correct answer: C
H-R diagram stands for the Hertzsprung-Russell diagram which was developed in the early 1900s by Ejnar Hertzsprung and Henry Norris Russell. The diagram plots the temperature of stars against their luminosity (the theoretical HR diagram), or the colour of stars (or spectral type) against their absolute magnitude (the observational HR diagram, also known as a colour-magnitude diagram).
