<span>The question is asking whether it is true that the defining characteristic of deserts is their high daytime temperatures. This is actually false, as deserts are defined as places with a very small precipitation - rainfall. In fact, the biggest desert on Earth is Antarctica, which is very cold! Some deserts are hot, for example Sahara, but not all of them.</span>
Mexico City is the location that has the highest population density. It is one of the most crowded cities in the world, so it is only natural that this is the correct answer here as well.
Answer:
4.54 km of earth's crust lies within mantel.
Explanation:
- Earth's continental crust is made of igneous, metamorphic, and sedimentary rocks and is composed of SIAL elements. The continental crust is made of various layers and has a density of 2.83 g/cm, while the oceanic crust is about 2.9 g/cm.
- The ontientla crust has usual thickness of 40 km (25 miles) thick and floats or rests on upper mantel or i.e the asthenosphere. While other parts of it lies within the mantel the depth of the continental crust ranges to 100 km,
- where r/25 = 2.7 / 3.2
- r/25 = 0.82
- r= 0.82 x 25
- r= 20.46
- 25 - 20.46 is 4.54 km.
They use colors to find regions so you can find them easyer.
