The boundaries of time zones correspond<span> roughly to lines of longitude
</span>This is why:
<span>The time in each successive time zone is one hour different from the times in neighboring time zones. To establish time zones,
Earth's rotation rate of 360 degrees of longitude per day was divided
by 24 hours. The result shows that Earth turns 15 degrees of longitude
per hour.
Hopefully I helped ^.^ Mark Brainly if possible~

Answer:
It would be an element my dear.
--------------------------------------------------------------------------------------------
Pure gold is an element. That is, it is not a combination of other materials. However, gold used in jewelry is usually a “mixture”, called an alloy mixed with other metals to harden it, to change the color as in copper makes the pink or rose gold that is currently enjoying great polarity.
Answer:francium
The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.
Explanation:
Answer:
Organism best adapted to the environment are able to survive in nature!
Explanation:
Suppose there was a green forest but after a volcano eruption all the green colored vegetation is lost and the area turns black . Now some organisms did survive...you have a black rat, and a white rat. You also have vultures flying in sky looking for prey. Overtime, the organism best adapted to environment can reproduce more and survive in nature. In our example, the black rats are the best adapted because their color matches with the environment so the eagles or vultures would have a hard time spotting them, whereas, a white rat in a black environment can be easily spotted so it has less adaptation to the nature.
