Eric said, “I took these photos from the same hill behind my house on three different nights. If half of the Moon is always illuminated and the other half is always dark, then why does the Moon look so different on different nights?”
Answers
Answer:
it is called waning and waxing It's because the moon is a world in space, just as Earth is. Like Earth, the moon is always half illuminated by the sun; the round globe of the moon has a day side and a night side. And, like Earth, the moon is always moving through space. it is also because of the position of the earth and the moon.

In carbonization, why is the fossilized material called a carbon film?
Answers
Answer:
When an organism dies or a leaf falls, it sinks into the earth's layers and decomposes. A carbon film is made when the oxygen, hydrogen and nitrogen of the organism disappear, leaving a thin layer of carbon. This process is known as distillation or carbonization.

How could you determine whether
an unknown substance is a mineral?
Answers
Answer:
you can classify a mineral by its appearance and other properties. The presence of a mineral is defined by the color and luster, and the color of the powdered mineral is described by the band. Every mineral has a distinctive density. To compare the hardness of rocks, the Mohs Hardness Scale is used.
Explanation:
Answer:
Luster, hardness , colour , clevage and magnetism
Explanation:
1. Luster makes sure the light is reflected by the mineral.
2. On the 10-point Mohs scale, which is basically a scratch test, hardness is measured. Take an unidentified mineral and scrape it like a fingernail with an object of known hardness.
3. Zurite, for instance, is often a deep blue, and malachite is gray.
4. In minerals that appear to divide along one or more flat surfaces or planes, cleavage may be observed.
5. Magnetite, for instance, has a heavy pull that even weak magnets can draw. But there is only a poor attraction to other minerals, particularly chromite (a black oxide) and pyrrhotite (a bronze sulfide.)

Why do you think these fossils are important to the study of evolution? Do you think the word transitional is a scientifically appropriate description for these fossils?
Knowing how fossils form, do you think it’s likely that humans will ever piece together a complete fossil record for every species that ever existed on Earth? Why or why not?
Answers
2. Yes the synonym of transitional is 'midway' and/or ;middle'. Transitional fossils are fossils that have traits of their ancestor and descendant. Thus these fossils exist between (middle) of their ancestor and descendant.
3. No, I don't think it is possible for all species that ever existed, because some fossils exist in places that humans cannot reach.
Answer:
Fossils tells a story of the relationship between the ancestors and this allows scientists to determine the common pattern in development. These fossils are also used to prove the theory of evolution. Yes the synonym of transitional is midway or also the middle. Fossils are fossils that have traits of their ancestor. These fossils exist between the middle of their ancestor.

Answers
The speed of the wind has increased throughout the day as there has been no precipitation.
What is precipitation?Precipitation is a process in which vapor of liquid changes into small droplets.
In the day time temperature of the atmosphere is high as compare to the night, so rate of precipitation is low at the day time due to which speed of the wind has increased as compare to the night time.
Hence, option (a) is correct i.e. there is no precipitation.
