Answer:
The Pacific Ocean is the largest and deepest of Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
I think this would be the Great Wall of China!
although it's actually thought to be much, much longer: over 5000 miles long, if yoiu include natural defensive barriers used in it.
Answer:
The Bulk density = 1.3 g/cm³
the porosity of the sample is 132 cm³
Explanation:
Given:
Volume of cylinder = 260 cm³
Mass of container and the soil = 403 g
Mass of the empty container = 65 g
Thus,
The mass of the soil is = 403 - 65 = 338 g
Now,
The Bulk density = 
or
The Bulk density = 
or
The Bulk density = 1.3 g/cm³
also,
average particle density for mineral soil is usually given as 2.65 g/cm³
i.e the air present in the given soil sample has reduced its density from 2.65 g/cm³ to 1.3 g/cm³
The mass of the whole sample = Volume × Density
= 260 × 2.65
= 689 gm
but,
The actual mass of the dry sample = 338 g
thus,
Mass of air in the sample = 689 - 338 = 351 g
Therefore,
the volume of 351 g soil = 
= 
= 132.45 cm³
so the porosity of the sample is 132 cm³
Cold fronts appear in areas of large temperature and air pressure decrease, whereas warm fronts appear in areas of Temperature and air pressure increase.
<h3>What are cold fronts?</h3>
Cold fronts are masses of atmospheric air that exert pressure on light warmer air masses, which then tend to rise in the atmosphere.
Cold fronts can be diagrammed in weather maps as blue lines and different triangular forms with sense to the region where they move.
In conclusion, cold fronts appear in areas of large temperature and air pressure decrease, whereas warm fronts appear in areas of Temperature and air pressure increase.
