Find the hot spot on the map. This represents one of the volcanoes of Hawaii, which gets its fuel because the island sits over a hot spot. Hot spots occurs at abnormally hot centers known as mantle plumes. Scientific models depict these plumes of molten rock almost like a lava lamp, with a rising bulbous head fed by a long, narrow tail that originates in the mantle. This type of volcanism, hot spot volcanism, is unique. Why?
A The hot spot volcanoes rarely result in mountain building; they are a destructive process.The hot spot volcanoes rarely result in mountain building; they are a destructive process.

how does the overfishing of lobster and snappers affect the amount of seaweed in the ecosystem?
Answers
Answer -Because of overfishing of the 2, it would allow the seaweed to overgrow meaning it could become invasive at some point. That means driving away or killing any other species that live in the said area.
Explanation
-Think about it like a garden. If you take away too many ladybugs from someone's garden. the aphid population would rise in the garden. Leading them to eat and destroy all the plants that were already there. like overfishing, if you take all the lobsters and snappers, the seaweed would grow and make all the other plants and species go away.
Overfishing has been identified as the most serious threat to coral reefs. Of the world's coral reefs, 55 percent are affected by overfishing.
Fishing is a major activity that can selectively remove large portions of animal populations and also significantly alter trophic interactions. Fishing gear that drags the bottom at times, such as bottom-trawls, pots, and longlines, can alter marine habitats, especially benthic or reef habitats.

Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.
crystallization
D.
mineral integration
Answers
it’s melting
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.
