Answer:
According to the core accretion model, initially the dust particles and the interstellar gases were all combined together forming a huge cloud, that eventually gets cooled and these gases got concentrated and became gradually denser.
Due to the increasing density, this cloud got disintegrated under the action of gravity, thereby formed a proto-star. Due to the continuous fusion and gravity effects, a star formed and eventually got burst. It then formed the sun with a disk of substances and matter around it. This rotating disc in due course of time gave rise to the planets that exist today.
This is how the solar system originated according to the core accretion theory.

The answer is D because the lithosphere is the crust of earth and the hydrosphere is the water on the earth.
Answer:
Option (1)
False
Explanation:
The mid-oceanic ridge is one of the main features in the divergent plate boundary. Seafloor spreading takes place along this ridge, where the lithosphere becomes thin because of the uprising magma. The magma erupts at the surface forming a ridge which is commonly known as the mid-oceanic ridge.
As the magma melts at this ridge due to the decompression process, it solidifies and forms young basaltic igneous rocks. These are geologically the youngest rocks. With the increasing distance right from the mid-oceanic ridge, the age of the rocks increases.
Thus, the correct answer is option (1).
At this mid-oceanic ridge, when the magma erupts at the seafloor, it is comprised of magnetic minerals, which shows a specific pattern in the orientation of the earth's magnetic polarity. This forms alternate stripes, that starts from the mid-oceanic ridge and eventually expand outward. This pattern of earth's magnetic polarity is found in all the mid-oceanic ridges on earth.
Hence the given statement is false.
