Which of the following statements is true?
Low pressure is usually means nice weather.
Air pressure is the same over the entire earth.
Worldwide winds are caused by rising air at the poles and sinking air at the equator.
Coastal breezes occur because water heats and cools more slowly than land.
PLEASE AT LEAST TRY PLEASE?
Answer:
1- Option (b)
2- Option (b)
3- Option (a)
4- Option (c)
5- Option (a), (b) and (d)
6- Option (d)
Explanation:
The equatorial region receives more sunlight than the polar region, so the places near equator are warmer than the places at the polar region, including the 80 degrees N latitude.
Seasons are caused due to the tiltation of the earth and the relative position of earth with respect to the sun.
Due to the increasing temperature near the earth's surface, the warm air rises up in the atmosphere, being less denser and eventually sinks due to the lowering temperature.
When there occurs the temperature difference between two different regions, then wind is generated blowing from the region of higher pressure to the region of low pressure.
Clouds are formed when condensation process takes place and are a good albedo that reflects significant amount of sunlight back into the space. Clouds during condensation starts precipitating in the form of rainfall, snowfall and fog.
The difference in the temperature occurs because of the unequal heating of the land surface and the ocean. The land area gets heated up faster and more readily, in comparison to the ocean. So the sea breeze as well as the land breeze occurs. Sea breeze blows from the ocean surface to the land area, whereas land breeze blows from the land area towards the oceans.
Answer: Osmosis
Explanation:
Osmosis can be defined as the phenomenon in which there is a difference in the concentration of materials on the different sides of the cell.
The concentration inside the cell is different and the concentration outside is different.
The membrane in between is the semipermeable membrane which allows the movement of certain molecules.
The movement of solvent takes place from a region of their higher concentration to the area of lower concentration via semipermeable membrane.
Answer: Osmosis
Definition: A process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
A.
oxygen
B.
nitrogen
C.
carbon dioxide
D.
methane
Yes, if she measures the volume and mass of all the pieces of the object, she should be able to calculate density.
Yes, if she measures the volume and mass of one of the pieces of the object, she should be able to calculate density.
No, once the object is broken apart and the shape has been altered, it is not possible to calculate the volume of the whole object to find density.
No, once the object is broken apart and the shape has been altered, it is not possible to calculate the mass of the object to find density.
pls is a quiz time
Answer:
the first one is a less than 3
the second one is c 9/4
Explanation:
b: the vinegar solution was hypotonic , causing the egg to lose mass
c: the vinegar solution was hypertonic , causing the egg to gain mass
d: the vinegar solution was isotonic to the egg so the mass remained constant
a) is the right answer
