A continental slope is a boundary between the Continental crust and Oceanic crust. Therefore, option (C) is correct.
What is a continental slope?A continental slope can be described as the slope between the outer edge of the continental shelf and the deep ocean floor. The continental slope is defined as a cut by submarine canyons in many locations and marks the seaward edge of the continental shelf.
Continental slopes follow the boundary between continental and oceanic crust. The Continental slope has a steepness range from 1 to 25 degrees, the average is 4 degrees.
The continental margin lies between the continental shelf and the abyssal plain and comprises a continental slope that is surrounded by the flatter continental rise. It contains thick sediments deposited by currents from the shelf and slope.
The shelf generally ends at a point of increasing slope known as the shelf break and the sea floor under the break is the continental slope.

What is a noble gas ?Any gas from the group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon and that exhibit great stability and extremely low reaction rates. — called also inert gas.
They have properties tending to an ideal gas.
It is asked that what volume will be occupied by 0.34 moles Helium Gas
The ideal gas equation is written as
PV = nRT
At STP , T = 273 K
P= 1atm
R = 0.0821 L(atm) mol⁻¹K⁻¹
Substituting the values
1 * V = 0.34 * 0.0821 * 273
V = 7.62 L
Therefore the volume occupied by 0.34 moles of Helium Gas is 7.62 L.

Explanation:
In going across a row of the periodic table, protons and electrons are added and ionization energy generally increases. In going down a column of the periodic table, protons and electrons are also being added but ionization generally decreases. Explain.
Answer:
Explanation:
Ionization energy:
It is the minimum amount of energy required to remove the electron from isolated gaseous atom to make the ion.
As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell.
When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required. Where as,
When we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
As the size of atom increases the ionization energy from top to bottom also decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

what is the molecular equation to AgNO3 (aq) + H2S(aq)?
There are two forms of chemical equations
Ion equation: written in ion form (as separated ions) which forms the net ionic equation after removing an ion spectator
Molecular equation: written in molecular form
2AgNO₃(aq) + H₂S(aq) ⇒ Ag₂S(s) + 2HNO₃(aq)
The above reaction can be included in a double replacement reaction⇒ an ion exchange between two ion compounds in the reactant to form two new ion compounds in the product
It can be shown the existence of the precipitation reaction, which is the formation of insoluble Ag₂S (not dissolve)

Which sentence uses pasteurize correctly?
The painter must pasteurize the scene in pastel colors.
The cows were put in the field to pasteurize.
They pasteurize the juice to make it safe to drink.
We decided to pasteurize the documents for safekeeping
Answer: C
Explanation: They pasteurize the juice to make it safe to drink.
The sentence which uses pasteurization correctly is that they pasteurize the juice to make it safe to drink.
What is pasteurization?Pasteurization or pasteurisation is a process of food preservation in which packaged and non-packaged foods (such as milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process.
The process is named after the French microbiologist Louis Pasteur whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine.Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety.

At $2.186/gallon, how many pennies would it cost to buy 125 L of gasoline? (1 gallon =
128 oz, 1 oz= 29.6 mL)
PLS HELPPPP
Answer : The cost of pennies to buy 125 L of gasoline would be, $71.92
Explanation :
As we are given that the cost to buy gasoline is $2.186/gallon.
Now we have to determine the cost to buy 125 L of gasoline.
First we have to convert 125 L into gallon.
Conversion used:
(1 gallon = 128 oz, 1 oz= 29.6 mL, 1 mL = 0.001 L)
As, 1 L = 1000 mL
So, 125 L = 125000 mL
and,
As, 29.6 mL = 1 oz
So, 125000 mL = [tex]\frac{125000mL}{29.6mL}\times 1oz=4222.9oz[/tex]
and,
As, 128 oz = 1 gallon
So, 4222.9 oz = [tex]\frac{4222.9oz}{128oz}\times 1\text{ gallon}=32.9\text{ gallon}[/tex]
Now we have to determine the cost to buy 125 L of gasoline.
As, the cost of 1 gallon of gasoline = $2.186
So, the cost of 32.9 gallon of gasoline = $2.186 × 32.9
= $71.92
Therefore, the cost of pennies to buy 125 L of gasoline would be, $71.92
Which of the aforement unique characteristics of earth do you like the most and why?
Answer:
The Earth rotates on its axis at a constant tilt.
Earths rotation on its axis at a constant tilt provides seasonal changes in the different part of the country. This resulted to the distribution of the heat of the sun from northern hemisphere and to southern hemisphere. Making areas with hot temperature may experience rainy season in a year. This will help production of crops or food supply and water supply available for living organism.
If the Earth's rotation is not tilted, then both the northern hemisphere and southern hemisphere will be covered with thick ice sheet. The equatorial region or near the equatorial region will experience tremendous warm temperature. Making our life on Earth not ideal for living.
Magnetic Field
Earth is protected by the magnetic from the dangerous radiation coming from the heat of the sun.
Water and oxygen
These two elements are essential for living organism in order to survive. The existence of waters proves that Earth temperature is conducive for living.
