How else can volcanoes form lakes?

Answer 1

Volcanoes are formed when cracks and fissures in the earth's surface allow molten rock, ash and gasses to escape from deep within the earth. When these eruptions happen the material cools above the earth's surface. Over many eruptions this can cause the volcano to form a mountain shape.

Answer 2

A volcano can cause a lake to form in 2 common ways: (1) A cone or crater is formed by the eruption. After the eruption(s) subside and the land therein begins to cool, water can fill the crater. An example is Crater Lake in Oregon. (2) The seismic and explosive nature of a volcano can cause landslides that block streams and rivers, forming a earthen dam. An example is when Mt. St. Helens blocked Coldwater Creek, forming an 8km long lake.

Answer 3

There are two may ways volcanoes can form lakes. First, the slopes of volcanoes are often unstable and prone to landslides. Landslides can create natural dams in rivers and streams, which in turn can create lakes. Second, after a particularly large eruption, some volcanoes collapse and form a depression called a caldera. Rainwater and snowmelt can collect in a caldera to form a lake.

Answer 4

It is like a bowl. It rains, snow melts, streams feed into it, so it fills up.

Answer 5

a lake forms by when it rains and the water never evaporates

Answer 6

In some extremely violent eruptions a volcano can collapses, forming a depression called a caldera. In some cases a caldera can fill with water, forming a lake.
