Answer:
The Romania and the Bulgaria to the west while the Ukraine, and the Russia, and the Georgia to the north and east, Turkey to the south
Explanation:
- Black sea is a body of water and a marginal sea and in the Atlantic ocean and is surrounded by the rivers such as the don, and the Danube. Having a maximum length of 1,175 km, and geologically it's divided into various basins as the west and the eastern basins.
- <u>Are surrounding this region has a black soil belt and is called as chernozem region. The sea is now for the oil and natural gas explorations and has sediment-rich nutrient water.</u>
A contour line (also isoline, isopleth, or isarithm) of a function of two variables is a curve along which the function has a constant value.[1] It is a cross-section of the three-dimensional graph of the function f(x, y) parallel to the x, y plane. In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level.[2] A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness of slopes.[3] The contour interval of a contour map is the difference in elevation between successive contour lines.[4]
More generally, a contour line for a function of two variables is a curve connecting points where the function has the same particular value. The gradient of the function is always perpendicular to the contour lines. When the lines are close together the magnitude of the gradient is large: the variation is steep. A level set is a generalization of a contour line for functions of any number of variables.
Contour lines are curved, straight or a mixture of both lines on a map describing the intersection of a real or hypothetical surface with one or more horizontal planes. The configuration of these contours allows map readers to infer relative gradient of a parameter and estimate that parameter at specific places. Contour lines may be either traced on a visible three-dimensional model of the surface, as when a photogrammetrist viewing a stereo-model plots elevation contours, or interpolated from estimated surface elevations, as when a computer program threads contours through a network of observation points of area centroids. In the latter case, the method ofinterpolation affects the reliability of individual isolines and their portrayal of slope, pits and peaks.<span>[5]</span>
Answer:
'Earth is the size of a tip of a ballpoint pen about 15 m away from the sun, is the correct answer.
Explanation
Radius of sun = 7 x 10^8 m
Radius of the earth = 6.37 x 10^6 m
Radius of grapefruit = 7.6 x 10^-2 m
Since sun is the size of a grapefruit.
So, our scale = (7.6 x 10^-2) / (7 x 10^8) = 10^-10
Means the scale is approximately, 1:10^-10
So, size of earth = 6.37 x 10^6 x 10^-10 = 6.37 x 10^-4 m (Size of ballpoint)
As we know that the distance between the sun and the earth = 14.9 x 10^10 m
So, in our scale, distance between the sun and the earth = 14.9 x 10^10 x 10^-10 = 14.9 m
which is approximately 15 meters.
Compared to the rest of the world, the US has the highest gdp of all countries. The number fell down drastically since world war 2, but the country still stays at the number one position.
