Some mountains are volcanoes, and some volcanoes are mountains, but not all mountains are volcanoes, and not all volcanoes are mountains. For a mountain to be a volcano and a volcano to be a mountain, it must be formed from magma and volcanic materials from below the Earth's surface.
Answer:
A globe
Explanation:
When we use a globe we can very accurately represent the Earth, its curvature, and with a good scale and coordinate system for the geography. This can be done on a map to an extent but in order for us to put a spherical body on a flat surface, we need to make some changes. This is why on maps you see some parts of continents as larger than they really are.
The mass number of an element is equivalent to the number of Protons and Neutrons in the element. For example Oxygen has eight protons and neutrons, therefore its mass number is 16. You could also calculate this by simply rounding the atomic weight of the element to the nearest whole number. Oxygen's atomic weight is 15.994, which as you can see, would be rounded to 16 :)
Because the world shifts slowly and can change imensly over time
I might be wrong, but I am pretty sure that the Mississippi River empties into the Gulf of Mexico. Hope I helped!!!
