Answer:
As the main sequence star glows, hydrogen in its core is converted into helium by nuclear fusion. When the hydrogen supply in the core begins to run out, and the star is no longer generating heat by nuclear fusion, the core becomes unstable and contracts. The outer shell of the star, which is still mostly hydrogen, starts to expand. As it expands, it cools and glows red. The star has now reached the red giant phase. It is red because it is cooler than it was in the main sequence star stage and it is a giant because the outer shell has expanded outward. In the core of the red giant, helium fuses into carbon. All stars evolve the same way up to the red giant phase. The amount of mass a star has determines which of the following life cycle paths it will take from there.

The life cycle of a low mass star (left oval) and a high mass star (right oval).
the different evolutionary paths low-mass stars (like our Sun) and high-mass stars take after the red giant phase. For low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf.

Answer:C They can lead to milder climates
Answer: Option (1)
Explanation:
When an oceanic plate collides with a continental plate, the denser oceanic plate gets subducted beneath the less denser continental plate, and this down-going slab undergoes partial melting at greater depth known as the subduction zone, which forces the magma to rise up and form volcano on the over-riding plate.
These volcanoes are of three types, namely the composite, dome and shield volcano. For example, Mount Vesuvius and Mount Fuji.
Thus, the correct answer is option (1).
In 1854, Ferdinand de Lesseps, the former French consul to Cairo, planned and constructed the Suez Canal of 100 miles across the Isthmus of Suez.
In 1875 <span>it was finished.
</span><span>When it opened, the Suez Canal was only 25 feet deep, 72 feet wide at the bottom, and 200 to 300 feet wide at the surface.</span>
