Sometimes it's hard to tell if the bowl-shaped feature at the top of a volcano is a crater or a caldera. you can usually determine if it's one or the other by
a. learning its size and how it formed
b . learning how much water it is filled with
c. learning what type of volcano it's on top of
d. learning if the volcano is active or extinct

A caldera viscous or acidic lava plugs the vent of a volcano this leads to violent eruptions this causes the crater to be blown off the top of the volcano subsides or collapes forming a basin shaped depression.called a caldera .hope this helps

Although this may be the opposite of what you think i will say it anyway. you were brought into this world for a reason and you still have soo much ahead of you. not everybody has an opportunity of living a great life, but it doesn’t give you a reason to end everything. somebody in the world loves you, and imagine what you would do to them if you left forever.
