Answer
An acid that breaks down completely and gives off many ions, or protons, is considered to be a strong acid. ex H₂SO₄
If you place strong acid into water it dissociate acid into H⁺ ions
Water is polar solvent(H⁺ and OH⁻), which has partial positive charge on one side and partial negative charge on the other side.
Strong acids readily dissociate in polar solvents to give H+ ions.
Where as Oil is a non polar solvent it has same charge all over so no dissociation of strong acid will take place.

Answer:
Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals can be found. At higher altitudes harsh environmental conditions generally prevail, and a treeless alpine vegetation, upon which the present account is focused, is supported. Lower slopes commonly are covered by montane forests. At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, desert, or tundra.
The largest and highest area of mountain lands occurs in the Himalaya-Tibet region; the longest nearly continuous mountain range is that along the west coast of the Americas from Alaska in the north to Chile in the south. Other particularly significant areas of mountain lands include those in Europe (Alps, Pyrenees), Asia (Caucasus, Urals), New Guinea, New Zealand, and East Africa. The worldwide distribution of mountain lands is shown in Figure 1.
