What condition results in magma cooling and forming a “glassy” igneous rock?
A)
extremely slow cooling
B)
cooling in the presence of oxygen
C)
extremely rapid cooling
D)
partial melt cooling
E)
extremely high pressure
Answer: C) extremely rapid cooling
Explanation:
When magma goes through extremely rapid cooling and especially if it did not dissolve enough water into it, it could freeze to glass or the mineral crystals that will be formed will be so small, they will look like glass.
This is because the reactions that occur to create minerals are affected directly by temperature such that if the magma cools down extremely slowly, it will form very large crystals but extremely fast would result in small crystals.

Chemical weathering occurs when minerals in rocks are changed chemically. Which of these will most likely change the rate of chemical weathering on a rock?
Group of answer choices
a. increase in rainfall amounts
b. slow movement of a glacier
c. rapid growth of plant roots
d. decrease in air temperature
Answer:
increase in rainfall amounts.
Explanation:
The one that is most likely to change the rate of chemical weathering on a rock is an increase in rainfall amounts. The correct option is a.
What is chemical weathering?Because the minerals present in rocks can change when they are exposed to substances like oxygen, carbon dioxide, and acids, it is the process by which rocks are broken down by chemical processes.
Accordingly, this type of rock breaking occurs as a result of chemical processes, as opposed to physical weathering, in which the rock breaks naturally without enduring any changes to its chemical composition.
It follows that physical weathering is the fragmentation of it without modifying its chemical or mineralogical composition, whereas chemical weathering is the chemical composition, according to the research.
Therefore, the correct option is a. increase in rainfall amounts.

When a u.s. company purchases and imports electronic parts from china to use to produce mp3 players within the united states, this purchase increases the component of gdp while also net exports by the same amount. therefore, the purchase of electronic parts from china causes in us gdp.?
Answer: investment; reducing; no net change
Explanation:
When a U.S. company purchases and imports electronic parts from China to use to produce mp3 players within the United States, this purchase increases the investment component of GDP while also reducing net exports by the same amount.
Therefore, the purchase of electronic parts from China causes no net change in US GDP.
The purchase of electronic parts from China will count towards Investment as the parts acquired will enable the company to produce goods.
As the purchase is from firms outside the country, it will count as Imports. Net Exports is calculated by deducting imports from exports so more imports reduce net exports.
With Investment going up and Net exports going down by the same amount, there will be no change in GDP as both Investment and Net Exports are components of GDP.
