Answer: Two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.
Explanation:
All stars (including the Sun) at birth begin to fuse two hydrogen nuclei to form helium through nuclear fusion.
In this sense, nuclear fusion is the union of two light atoms, releasing energy in the process, which is the cause of the great luminosity of a star. Especifically, the hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.
To unerstand it better:
To shine, the stars transform their hydrogen into helium by means of nuclear fusion. When at half of its life a star is without hydrogen, the nucleus becomes entirely helium and the star declines, becoming colder and brighter due to the energy generated by the nuclear reactions, then the star begins to contract.
Nevertheless, if the star is bigger, this helium will be also consumed and the nucleus transformed in Carbon, then in Oxigen, and so on. Being the last transformation Iron until the star delivers all its energy.
Answer:
=>Option A is correct
Explanation:
Occasionally earthquakes occur as a result of collisions along oceanic-continental convergent boundaries.
=> The closer it is to the edge between ocean and continent, the more likely earthquake occurs.

Answer:
The fault lines pull away from eachother and it breaks up into blocks r chunks which are either forced upwards or downwards. As hey move apart these chunks or blocks end up being stacked ontop of one another causing a fault block mountain as the fault lines have been blocked up. An example of a faultblock mountain are the Sierra nevada mountains in North America.

Answer:
The Asian elephant is the largest land mammal on the Asian continent. They inhabit dry to wet forest and grassland habitats in 13 range countries spanning South and Southeast Asia. While they have preferred forage plants, Asian elephants have adapted to surviving on resources that vary based on the area.
Asian elephants are extremely sociable, forming groups of six to seven related females that are led by the oldest female, the matriarch. Like African elephants, these groups occasionally join others to form larger herds, although these associations are relatively short-lived. In Asia, elephant herd sizes are significantly smaller than those of savannah elephants in Africa.
More than two-thirds of an elephant's day may be spent feeding on grasses, but it also eats large amounts of tree bark, roots, leaves, and small stems. Cultivated crops such as bananas, rice, and sugarcane are favorite foods. Elephants are always close to a source of fresh water because they need to drink at least once a day.
In Asia, humans have had close associations with elephants over many centuries, and elephants have become important cultural icons. According to Hindu mythology, the gods (deva) and the demons (asura) churned the oceans in a search for the elixir of life so that they would become immortal. As they did so, nine jewels surfaced, one of which was the elephant. In Hinduism, the powerful deity honored before all sacred rituals is the elephant-headed Lord Ganesha, who is also called the Remover of Obstacles.
