The correct answer is - B. rainfall and chemical reaction.
The Great Buddha statue is under constant change and it is slowly but surely weathering bit by bit. The two biggest reasons for this are:
- The rainfall; the water from the rainfall is one of the biggest causes of weathering of the rocks, the water is known to decompose the rocks over time and the Great Buddha statue which is on an open space is not an exception of its influence.
- The chemical reactions; China has a huge problem with pollution. There's lots of pollutants in the air that are causing serious damage to most things, including the Great Buddha statue, and they contribute to quicker decomposing with their corrosive power and change in colour than anything else.
b. the condensation cycle.
c. precipitation.
d. evaporation.
The answer is A- Water cycle. The only way i can explain the water cycle is that it basically describes how water is constantly circulating on, above, and below the earth.
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.

Answer For the last quarter century or so, the leading theory of the driving force behind tectonic plate motions visualized large scale convection currents in the upper mantle.
B the upper class
C the working poor
D the middle class
Answer: the working poor
Explanation:
Jacob A. Riis was a journalist and he was also a social reformer. In the 19th century, he publicized the challenges that people faced with regards to housing and poverty.
He used his writing to expose the hardship that immigrants faced and the plight and poverty among them. He took photograph of their saloons, slums, etc that the working poor in New New York were faced with.
The other half” that Jacob Riis referred to in his 1890 book How the Other Half Lives were the working poor.
Answer:
the working poor
