Why do different places on Earth have different climates?
Your answer should include 1 paragraph to explain the claim, evidence, and reasoning. Be sure to check your grammar and spelling!
First, the amount of sunlight received at a given latitude is important. At the equator, the sun is high in the sky and thus very intense. As you move away from the equator, the sun does not reach as high of an angle in the sky, and is less intense. Another important effect near the poles is that during the summer, the sun is up all the time, which boosts the total amount of sunlight received in a day, while in contrast, during the winter, no sunlight is received at all.
There is another, more subtle effect that has to do with latitude. Nature likes to have the temperature be the same everywhere, much like ice cream melts at room temperature or a hot cup of coffee cools to room temperature. The equator is getting blasted with intense sunlight, while the poles are getting a lot less. Nature tries to resolve this imbalance and make the atmosphere the same temperature everywhere. The most efficient way to transfer heat towards the poles depends on latitude and the rotation of the Earth in a complex way. In the tropics (within 30 degrees latitude of the equator), the average daily temperature is mostly constant. Whether you move from north to south, say fro the equator to Mexico, the temperature is mostly the same. Compare that to the midlatitudes (30–60 degrees latitude), where the temperature changes rapidly as you move north or south to the poles. For example, the temperature in Texas is a lot hotter than the temperature in North Dakota.
Another factor is the composition of the surface. Different substances absorb, store, and re-emit heat with different levels of efficiency. The ocean is a major factor, which can either warm or cool the adjacent land. Other surface materials like rock, sand, vegetation, and ice also regulate temperature
The elevations of the surface, specifically mountains effect the climate. Usually, the taller the mountain, the colder the temperature is at the top. Mountains also cause air to flow in certain ways around them, which leads to wet areas on the upwind side and dry areas on the downwind side.

Answer:
Some advantages to using hydrokinetic energy are that it can be used without mining materials, it is not associated with waste production, and that it does not contribute to air pollution. The main disadvantage to using hydrokinetic energy is the fact that it uses waves and tides as an energy source. This technology could not be used in all locations.

What mass of aluminum must react with 100 g of copper (ii) phosphate? (10g)
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity or amount of substance. We know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number.
Mathematically,
mole =given mass ÷ molar mass
2 Al + 3 Cu[tex]_3[/tex](PO[tex]_4[/tex])[tex]_2[/tex] → Al[tex]_2[/tex] (PO[tex]_4[/tex])[tex]_3[/tex]+ 3 Cu
moles of copper phosphate= 100 g/380.58
=0.26 moles
3 moles of copper sulphate need 2 mole of Al
0.26 moles of copper sulphate need (2/3)×0.26
=0.17moles
mass of Al= 0.17×26
=4.42g
Therefore, 4.42g of aluminum must react with 100 g of copper (ii) phosphate.

Answer:
6.6242 x 10 ^ 24
Explanation:
This is the correct answer because you know there is 11 oxygen moles in 1 mole of sugar so using dimensional analysis you can solve it. You start will 11 moles of oxygen, and multiply by Avogadro's number(6.022 x 10 ^23) to get the amount of atoms. I don't see it as an answer, but I am confident in this, so I would ask your teacher specifically.

Based on seismometer data what kind of information can seismologists calculate?
location, quantity, and time of damage created by earthquake
track movements of magma in the Earth's mantle and find out when volcanos will erupt
the distance of the earthquake's epicenter, the location of the epicenter, and when tsunamis will strike coastal areas
time of earthquake, magnitude and velocity, and type of seismic waves
Answer:
Time of earthquake, magnitude and velocity, and type of seismic waves
Explanation:
Seismometers allow us to detect and measure earthquakes by converting vibrations due to seismic waves into electrical signals, which we can then display as seismograms on a computer screen. Seismologists study earthquakes and can use this data to determine where and how big a particular earthquake is.

your answer.
No, input energy is not equal to useful output energy, if it is an electric toothbrush.
What is the useful type of energy produced in an electric toothbrush?Electrical Energy is the useful type of energy produced in an electric toothbrush.
If input energy is equal to useful output energy. This means that the total amount of energy that is in an isolated system (such as an engine or a generator) remains constant (conserved) over time.
However, the total amount of useful energy output of an isolated system is never equal to the total energy input.

1) How many moles of hydrogen gas can be produced if 0.57 moles of hydrochloric
acid, HCl, reacts with excess solid zinc according to the following chemical
equation?
2 HCl + Zn → Hz + ZnCl2
Answer: 0.28 mol H2
Explanation:
0.57mol HCl 1mol H2
2mol Hcl
Hydrochloric acid and zinc show the displacement reaction to produce hydrogen gas and zinc chloride. 0.57 moles of hydrochloric acid and excess zinc react to produce 0.28 mol H₂.
What is a displacement reaction?A displacement reaction is the removal of one of the elements from the reactant with highly active species of the reactivity species to produce the products. It can be a single or double displacement reaction.
The balanced chemical displacement reaction is given as:
2 HCl + Zn → H₂ + ZnCl₂
Here, two hydrochloric acids react with zinc to form one mole of hydrogen gas and one mole of zinc chloride.
Given,
Hydrochloric acid = 0.57 moles
Using proportions to calculate moles as:
If 2 moles of HCl = 1 mole H₂
Then, 0.57 moles = X moles
X = 0.57 ÷ 2
= 0.28 mol H₂
Therefore, 0.57 mole HCl produces 0.28 moles of hydrogen gas.

How many molecules are in 10 grams of sulfur hexafluoride (SF6)? Molar Mass: 146.06 g/mol
Answer: 4.123 x 10^22
Explanation:
The first step is to determine how many moles of sulfur hexafluoride (SF6) there are. To do this, you must take the mass of the SF6 (10g) and divide it by the molar mass (146.06).
[tex]10g * \frac{1 mol}{146.06 g}= 0.068465 mol[/tex]
Then you must use Avagadros number to find the number of molecules.
Avagadros number is the number of molecules in 1 mol of a substance, so a simple multiplication will do the trick.
[tex]0.068465mol * \frac{6.022 * 10^{23}}{1mol} = 4.123*10^{22}[/tex]
And that is your answer. There are 4.123 x 10^22 molecules of sulfur hexafluoride in 10g of it.

A sample of gas occupies 20 mL at -109 degree C. What volume does the sample
occupy at 65 °C?
Answer: V2= 41.2mL
Explanation:
Givens:
* V1= 20ml
* T1 = -109 ⁰C --> K= ⁰C + 273.15 --> 164.15 K
* V2 = ??
* T2= 338.15 K
Use Charles law V1/T1 = V2/T2
Since we are looking for V2 we can rearrange the formula to
V2= (T2 x V1) /T1
V2= (338.15K x 20mL) / 164.15 K
V2= 41.2mL
NOTE:
Temperature should always be in K not in ⁰C or ⁰F
To convert from C to K use
*K= ⁰C + 273.15
Enter your C value in the ( ⁰C ) and you can get K
