How does crater lake effect the environment?
Crater Lake affects the environment by attracting tourists who leave litter in the area. This then causes pollution and even affects the wildlife by disturbing mating and nesting in the area.
Depends on which Crater Lake you are asking about. A Crater Lake can be caused by two different things, 1, a volcano, 2, a large impact crater such as a meteor strike. A good example of a volcano lake would be Crater Lake in Oregon. While the impact craters forming lakes are not generally known as crater lakes, a good example of this is Lake Manicouagan in Quebec.
