a. Lithification and Erosion
b. Heat and pressure
C. Compaction and weathering
d. Cooling & Crystallization
Answers
Answer:
d. Cooling & Crystallization
Explanation:
One of the stages of the rock cycle that can take place under mere hours or days is cooling and crystallization.
Cooling and crystallization of lava on the earth surface is a very rapid and fast process.
When magma from within the earth reaches the surface, it becomes lava. Due to the nature of the surface, it cools rapidly and very fast to form very fine grained igneous rocks.

If ice is added to a large fish tank and a small fish bowl, both at the same termperature, the large fish tank's water will cool faster because there is more water.
TRUE OR FALSE
Answers
because the smaller bowl of water has less volume to cool off with the ice than the large fish tank
Answer: False
Explanation:
When a object is touching a surface, it mostly likely will change the temperature it's on, depending on how it is. Since they both have different temperatures and cooling down at the same particularity rates, it is highly false that this would happen. What WOULD would the bowl cool faster THAN the water, then the ice will transform into water.

Explanation:
The atoms of elements on the same period on the periodic table typically have the same number of valence electrons.
They have the same electronic configuration.
Valence electrons are electrons in the outermost shell of an atom.
The number of electrons in an atom is a good indicator of elements that might potentially belong to the same group.

Which statement best explains how the gases of the atmosphere affect the temperature of Earth?
A
The gases reflect all of the heat from the Sun, preventing it from reaching Earth's surface.
B
The gases absorb all of the heat from Earth's surface, preventing it from radiating into space.
С
The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface.
D
The gases reflect some of the heat from Earth's surface, holding it away from the surface in space.
Answers
Answer: The answer is c
Explanation:
The gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.
What is atmosphere?Atmosphere is defined as a layer of gas that surrounds a planet and is kept there by the gravitational pull of the planetary body. The atmosphere of the earth shields its people by absorbing dangerous sun rays and preserving a constant temperature. It protects Earth from many space hazards and enables life there. As a result, it is crucial for regulating climate and a source of life on planet.
The majority of the infrared energy from the Sun is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds, creating the greenhouse effect. This causes the lower atmosphere and the Earth's surface to warm.
Thus, the gases absorb some of the heat from the Sun, holding it to keep it warm near Earth's surface. Hence option C is correct.

How many moles of Fe2O3 were used to produce with 11.5 moles of CO2 ?
Answers
Moles of Fe2O3 used : 3.83
Further explanationGiven
11.5 moles of CO2
Required
moles of Fe2O3
Solution
Reaction
Fe2O3 + 3CO ⇒2Fe + 3CO2
The reaction coefficient shows the mole ratio of the reacting compound (reactants or products)
From the equation, mol ratio of Fe2O3 : CO2 = 1 : 3, so mol Fe2O3 :
= 1/3 x moles CO2
= 1/3 x 11.5
= 3.83 moles
