The correct answer is - barchanoid dunes.
The barchanoid dunes are a variety of dune intermediate between barchan dunes and transverse dunes. The barchanoid dunes are recognizable for the formation of scalloped rows of sand that are perpendicular to the wind that brings in the sand material with it.
Answer:
Option (3)
Explanation:
The contour lines are lines of equal elevation, from the mean sea level. This contour lines are often shown in the topographic maps with lines and are separated from one another by a fixed vertical distance. These contour lines never intersect each other. In a topographic map, closely spaced contours depicts a steeper slope, whereas widely spaced contour lines depicts a gentle slope.
Thus, the correct answer is option (3).
Answer:
1. The temperature of the inner core is far above the melting point of iron. However, unlike the outer core, the inner core is not liquid or even molten. The liquid outer core separates the inner core from the rest of the Earth, and as a result, the inner core rotates a little differently than the rest of the planet.
2. Like the shell of an egg, the Earth's crust is brittle and can break. ... As a comparison, the mantle might be thought of as the white of a boiled egg. At the center of the Earth lies the core, which is nearly twice as dense as the mantle because its composition is metallic (iron-nickel alloy) rather than stony.
3. What is the difference between the crust and lithosphere? The crust (whether continental or oceanic) is the thin layer of distinctive chemical composition overlying the ultramafic upper mantle. The lithosphere is the rigid outer layer of the Earth required by plate tectonic theory.
There you go I hope this helped you have a great day! :)
