Answer:
The Himalayan mountain is formed at the convergent plate boundary.
Answer: Evaporation and condensation are the two changes in state which are most represented in water cycle.
Explanation:
A process of circulation of water by passing through different states between the atmosphere, oceans and land is known as water cycle.
In water cycle, the most represented changes in state are evaporation and condensation. As during evaporation, the water present in the oceans, rivers, wells or on the land evaporates because of the heat from the sun as a result the liquid state is changing into gas.
Whereas, during condensation gas or water vapours changes into liquid. For example, when water condenses in the atmosphere it results in the formation of clouds.
Thus, it can be concluded that evaporation and condensation are the two changes in state which are most represented in water cycle.
My answer will be C. Law of Original lateral continuity. :)
Answer: Option (D) is the correct answer.
Explanation:
The chemical reaction equation will be as follows.

This means a new substance has been formed and a chemical change has taken place.
A chemical reaction in which heat energy is absorbed by the reactant molecules is known as an endothermic reaction.
For example,
On the other hand, a chemical reaction in which heat energy is released by the reactant molecules is known as an exothermic reaction.
For example,
is an exothermic reaction.
Thus, we can conclude that in the given situation the beaker most likely felt warm because a chemical reaction was producing a new substance.
