<u>Answer:</u>
The law of demand states that "price decreases lead to greater demand and limited supply, which occur during excess demand" explains the relation between the law of "demand and excess demand".
<u>Explanation:</u>
- The "law of demand" states that when the "price of a commodity decreases", there is a relative surge in the demand for the commodity.
- Owing to greater demand, the supply falls short and is thus termed as 'limited'.
- This happens because when the price decreases, the affordability of the commodity increases and the number of customers willing to buy the commodity automatically increases.
In order for a plant to be a plant it has to grow and it need its energy to help the plant grow
Answer:
Option B
Explanation:
Tuttle and Bowen conducted a study in 1958 after which the study of modern granite started. They also determined whether granite is igneous rock or not. Some of the prominent remarks that were concluded after the experiment by Tuttle and Bowen are
- A) When a silicate is melted at lower temperature, it contain equal proportions of Ab, Q and Or
- B) Felsic rock form at the end of the fractional crystallization of mafic rock
C) Determined the temperature and pressure at which high and low granite crystal melts and what is the impact on melting if Ab, Q and Or are present
The melting temperature of materials is affected by the pressure they are under. So when "rock" in the Earth's mantle experiences a decrease in confining pressure, not only does it expand, it's melting temperature drops. If the melting temperature of the material drops below the background (also known as the
in-situ
) temperature, then melting will occur and in this case magma will form.
