Answer: The answer is D.gram
Explanation:
Do you mean "deciding when the continents shifted"? If so, the fossils of fish and other animals found in mountain belts show when water was surrounding a certain landmass. From here scientists can determine when this land mass separated.
Because it is a lot closer to us then any of the stars are....
You may have noticed that the nearer a thing is to you, the larger it looks,and the farther.
Answer:
10% solution volume
=7.5 L
30% solution volume = 2.5 L
Explanation:
assume 10% solution volume is x
So 30% solution volume = 10-x
Required 15% solution= x volume of 10% solution+ (10-x) volume of 30% solution
0.15 * 10L= 0.1 x + (10- x)* 0.3
1.5= 0.1 x+ 3 -0.3 x
0.2 x= 1.5
x= 7.5
10% solution volume is x
=7.5 L
So 30% solution volume = 10-x = 10-7.5= 2.5 L
It is false
Precipitation - What makes clouds, rain, snow, hail and sleet. When warm, wet air rises, it cools, and water vapor condenses out to form clouds. A cloud is made up of small drops of water or ice crystals, depending on its height and how cold is the surrounding air.
