How does volcanic activity shape the Earth?

please help me please help .
​

Volcanic activity shapes the Earth by making mountains, new landforms or even islands in the ocean. they can create jungles or they can destroy jungles and other ecosystems that are easily living and doing just fine. but sometimes it's good that the volcanoes ( lava ) destroys some ecosystems because then it makes room for better and new ecosystems for the animals.
