Answer:

They´re a source of invaluable information. The study of these cosmic materials allows us to gain knowledge about the history of the solar system, about processes and primary conditions in the universe. We can learn the age and the composition of the planetary building blocks, the temperatures reached at the surface and interiors of asteroids, what kind of effect do materials experience due to impacts in the past.

Which statement is true about the waxing gibbous moon versus the waning gibbous moon?
hram777 [196]

Answer:

All of the above is true about the waxing gibbous and waning gibbous moon.

Explanation:

The first option is correct because the waxing gibbous moon is lit up on the right, with the moon moving into full moon phase next, and then being followed by a phase where it is lit up on the left, known as the gibbous waning moon.

The second option is correct because the moon moves from the waxing gibbous phase toward the full moon phase, it is becoming more and more lit up, thus it gains light, while the waning gibbous moon phase comes after the full moon phase where it is becoming less and less lit up, thus loses light.

The third option is correct because the lit up part of the moon in both of these phases has an elliptical shape, with the elongated part being on the top and bottom side, thus giving it an appearance like a football.

A mineral is generally defined as a naturally occurring solid chemical compound which is present in its pure from. A substance is said to be a mineral, if it satisfies the following five criteria: <u>naturally occurring, solid, inorganic, ordered internal structure, definite chemical composition.</u>

Therefore, a mineral is a naturally occurring solid inorganic substance with a well-defined chemical composition and specific crystalline structure.

<u>Therefore, we can say that</u><u> texture</u><u> is not one of the criteria that defines a mineral.</u>
