Answer:
9:00 am
Explanation:
Lines of longitude are imaginary lines running from the north pole to the south pole of earth. These lines are used to calculate the time in places. Also when combined with lines of latitude, they are used to give the exact location of a place.
Given the place is at 45°W longitude and the time at GMT is 12:00 noon.
Degree difference = 0° (GMT) - 45° = -45°
1° = 4 min
time difference = -45° * 4 min per degree = -180 minutes = -3 hours
Therefore the local time at a place 45°W longitude = 12:00 noon - 3 hours = 9:00 am
True the demography is the scientific study of population characteristics
Answer:
By switching to a company that provides electricity from solar, wind, or hydroelectric energy, you can reduce your household emissions and save money on your energy bills. You could even install solar panels if they're readily available where you live.
The statement is - True.
The solvent do contains chlorofluorocarbons (CFC) and hydrochlorofluorocarbons (HCFC) which evaporate and enter the atmosphere. Because they are very light, the CFC and HCFC manage to get very high into the atmosphere, reaching the ozone layer in the stratosphere. They are actually the two substances that are the most damaging to ozone layer, as once they get in touch with it, they break down its structure, thus creating the ozone holes.
The ozone is crucial for the survival of the living organisms on the Earth as it is the layer that manages to stop most of the ultraviolet rays form the Sun to reach the surface. Because of that, these two substances have to be replaced quickly as the ozone layer is becoming more and more damaged, and that can eventually lead to a tragedy.
Answer:30%
Explanation:It shares the continental landmass of Eurasia with the continent of Europe and the continental landmass of Afro-Eurasia with both Europe and Africa. Asia covers an area of 44,579,000 square kilometres (17,212,000 sq mi), about 30% of Earth's total land area and 8.7% of the Earth's total surface area.
