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°

Answer: The Turquoise Lake as seen nowadays in Colorado is a result of the 1850´s modern warming climate transition, lingering away from the Little Ice Age times occurred 500 years ago. This given period was characterized by snow blowing winds that accumulated ice through thermal compaction, generating the glaciers as we see them.
Explanation: Terminal and recessional moraines are the terminus of a glacial feature. Moraines are the sedimentar charges carried by melted glacials. Consequence of those is the repositioning of the snow downwards the valleys. The ice, initially attached to the glaciers and mountain tops, undergoes melting by seasonal and/or climate transition warming, resulting on circumstancial water deposits that place on the basin/lower areas of the mountain chains, forming lakes.
Answer:
The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
Explanation:
The answer is : 74 Mph Or Greater
A tropical storm can turn into hurricane when wind speed goes above 74 miles per hour, which give it enough forces to destroy a hard concretes buildings that it passed by
