Answer:
Algunas son naciones lindantes, como Argentina, Australia, Chile y Nueva Zelanda. Pero también tres países europeos -Francia, Noruega y Reino Unido- reclaman soberanía sobre sectores de la Antártida.
Answer:
Because Earth's gravitational pull is so strong, we do not notice the pull from other objects. Earth's gravity pulls everything to the center of Earth and prevents us from flying off into space
The difference in elevation in meters between the points X and Y is 360.
Explanation:
On the presented map we can see that the relief is depicted with contour lines. The contour lines are marked with their elevations, or rather the main contour lines are, every fifth one. We also have the contour interval, which is 20 meters, thus giving us the basis so that we can find the difference in elevation between any points on the map.
What we know for sure from the map is:
- the elevation is increasing from southeast toward northwest
- the difference in elevation between the contour lines is 20 m
- the difference in elevation between the main contour lines is 100 m
Point X is marked on the contour line of 1,600 m. Point Y is marked on the second contour line between the 1,200 m and 1,300 m contour lines, thus:
2 x 20 = 40
So we have 1,240 m. Having the elevations of the two points, we only need to take the lower value from the larger value:
1,600 - 1,240 = 360 m
So we get a result of 360 m of difference in elevation between the points X and Y.

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
