Answer:
Option (2)
Explanation:
The earth's interior is divided into 3 parts which includes the crust, core and the mantle. The core of the earth represents the extreme interior part of the earth which is covered by the mantle. The density of the core is the highest and is approximately 13 g/cm³, Whereas, the density of the mantle (including both the upper and lower mantle) is relatively less and is about 4.5 g/cm³ on an average.
The asthenosphere is the layer in which the rocks are solid but they tends to flow during deformation. This layer is present in the apex portion of the upper mantle and it has a density of nearly 3.3g/cm³.
The continental and the oceanic crust represents the outermost portion of the earth. The rocks of oceanic crust are denser than the rocks of continental crust. The density of the oceanic crust is nearly 3 g/cm³ and continental crust is 2.7g/cm³.
Thus, the continental crust is the less dense, compared to the other layers of the earth.
Hence, the correct answer is option (2).
Answer:
Explanation:
With less gravity, it is harder to keep your body strong. If the Earth's gravity is lost, all items held to the Earth's surface by gravity would float away. That includes the atmosphere, water, people, cars and animals. If an object were secured strongly to the Earth, it would probably remain attached depending on how strong it is.
Explanation:
The "doldrums" is a descriptive adjective for the corridor from around Earth closer to the equator when ships can become stuck in windless seas. In the horse elevations, where even the air moves down to towards the Earth's surface, the increasing jet stream eventually subsides.
