7. What is a hotspot? A location in Earth's atmosphere with high temperatures

where molten magma rises to just underneath the surface of Earth, creating a bulge
or volcanic activity

where many minerals can be found naturally beneath the surface of Earth

a location in the ocean where water is heated by vents in the ground

It is B

Explanation:

The magma created from the heat pushes through cracks and forms volcanoes

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
