Because there are 2 types of igneous rocks:- •Intrusive rocks-are rocks when the magma cool’s down before reaching the surface of the earth. •Extrusive rocks-are rocks when magma cools down after reaching the earths surface. So their composition can be different because of the formation of the rocks at different places. Eg:-Granite rock:-intrusive rock. Basalt:-extrusive rock
Answer:
Pre-dusk, early to medium twilight phases allow outdoor activities without using artificial lighting
Explanation:
Civil twilight is a term, and we describe it as "the time after sunset and before sunrise ends or begins when the sun seems to be about 6 degrees underneath the horizon during which the light for normal outdoor occupations is adequate on clear days.
Nautical twilight is the second stage of twilight. By this time, both horizon and the brighter stars are easily visible, making navigation around sea possible.
Astronomical twilight occurs whenever the Sun is under the horizon between 12° and 18°
