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 country was once known as the breadbasket of Europe, owing to its large agricultural industry.
Explanation:
Answer:
When the entire lake reaches 40 F, the surface water cools further, dropping below 40 F. Because this water is now less dense than the surrounding water, it will stay on the top and continue to cool. Once the surface water falls to 32 F, it freezes. The freezing then spreads downward into the lake and the ice thickens
Explanation:
Answer: (b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others with the Sun at precise center of the ellipse. Minor axis is the same as other ellipses.
Explanation:
According to the first Kepler Law of Planetary motion, the orbit of a planet around the Sun, is in the form of an ellipse <u>with the Sun at one of the two foci of that ellipse</u>. This is also valid for any mass orbiting another mass greater than the first one in the space.
In this context, the ellipse is a conic, whose eccentricity is between 0 and 1. So, when its value is 0 we are talking about a circular orbit and when it is 1, a parabolic orbit.
That is, the nearer to the value of 1 (without reaching 1) the eccentricity of the orbit is, the more elliptical it will be.
In this sense, the only option that is incorrect is:
(b) Planet orbit shown as a moderately-flattened ellipse slightly wider than the others <u>with the Sun at precise center of the ellipse</u>. Minor axis is the same as other ellipses.
This statement contradicts Kepler's first law, because the Sun is <u>at one of the two foci of that ellipse</u>. The only way in which the Sun can be at the very center of the orbit is when we talk about a circular orbit. Since a circumference is a especial case of an elipse with eccentricity zero and we get only the center instead of the two foci.
Fairly sure we go to the same hs but I put A. It might be c though. Not totally sure.
