Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface. I think its B
Answer:
oceans transfer energy from the sun. They do so , in order to exchange heat and moisture to the sky and earth influencing weather systems accordingly.
The ocean influences weather patterns by distributing heat and moisture around the globe. ... Tropical storms form over warm ocean waters, which supply the energy for hurricanes and typhoons to grow and move, often over land. The winter storms that bring precipitation to the western U.S. originate over the North Pacific.
Why is the ocean water near the poles less salty than other places?
Question 8 options:
Rain washes mineral ions from the land into water.
Fresh water from the glaciers are melting into it.
Active underwater volcanoes erupt nearby.
Earthquakes shake rock loose nearby.
Answer:
Rain washes mineral ions from the land int water.
Explanation:
The amount of rain is highest at the equator and lowest at the poles. Due to this heavy amount of rain at the equator areas minerals get washed from land to the water. The washed minerals when be in the watery medium the either dissolve or dissociate to different ions according to their nature. The dissolution or dissociation of minerals in the water releases various salts in the medium and it becomes salty because of their presence in higher amounts.
Answer:
Fresh water from the glacier are melting into it.
Explanation:
Fresh water, in the form of water vapor, moves from the ocean to the atmosphere through evaporation causing the higher salinity. Toward the poles, fresh water from melting ice decreases the surface salinity once again. ... Adding salt to water lowers the freezing temperature.
how is a series circuit different from a parallel circuit?
A series circuit has two or more loops and a parallel has only one loop for the current to flow through.
A series has an open circuit and a parallel circuit has a closed circuit
A series circuit has only one loop and a parallel circuit has two or more loops for the current to flow through
A series circuit has a closed circuit and a parallel circuit has an open circuit.
Answer:
C. A series circuit has only one loop and a parallel circuit has two or more loops for the current to flow through
Explanation:
A circuit that are made of one loop is called series circuit. On the other hand, the parallel circuit has at least two loops. The circuit type has nothing to do with open or closed circuit.
If any part of the series circuit got cut, the current will stop flowing since there is only one loop. A parallel circuit has more loop so the circuit might still work even if a part of the circuit got cut.

A gas that has a volume of 28 liters, a temperature of 42°C, and an unknown pressure has its volume increased to 49 liters and its temperature decreased to 27°C. If the pressure is measured after the change at 4.0 atm, what was the original pressure of the gas?
Answer:
7.35 atm
Explanation:
From the question we are given;
Initial volume, V1 as 28 LInitial temperature, T1 as 42°C or 315 KNew volume. V2 as 49 LNew temperature, T2 as 27°C or 300 KNew Pressure, P2 as 4.0 atmWe are required to determine the initial pressure, P1
We are going to use the combined gas law...
According to the combined gas law,
[tex]\frac{P_{1} V_{1} }{T_1} =\frac{P_2V_2}{T_2}[/tex]
Therefore, to get P1
[tex]P_1=\frac{P_2V_2T_1}{V_1T_2}[/tex]
We get;
[tex]P_1=\frac{(4.0)((49)(315)}{(300)(28)}[/tex]
[tex]P_1=7.35[/tex]
Therefore, the initial pressure of the gas is 7.35 atm
20ml of 2M KOH are placed into a beaker. 4M CH 3 COOH are placed into a burette.
a. Predict what volume of CH 3 COOH will be needed to neutralize the KOH.
Volume of CH3COOH will be needed to neutralize the KOH is 10 ml.
Explanation:
In the titration process the concentration of unknown analyte be it acid or base is calculated by the formula:
Macid x Vacid = Mbase x Vbase equation 1
Data given:
volume of base KOH = 20 ml
molarity of base = 2M
Molarity of CH3COOH acid = 4 M
Volume of CH3COOH acid = ?
Putting the values in the equation 1
4 x V acid = 20 x 2
V acid = [tex]\frac{40}{4}[/tex]
V acid = 10 ml
The neutralization of KOH by CH3COOH will be done by using 10 ml of 4M solution of CH3COOH against 20 ml of 2M KOH.
