Mountains

Everyone knows that mountains are a well known part of the lithosphere. Name a unique mountain and what makes it so unique. This can include a chain of mountains or just a single mountain. Please no repeating. :-)

Hydrosphere

Which natural under water feature do you find the most interesting? Name the feature and why it's interesting. If it has a function in some way explain. Also if it moves or goes off or something, explain what this is and how it happens.

Tornadoes

Tornadoes are a deadly and almost unpredictable event. They are created from high winds during thunderstorms and other such fierce rain storms, as well as some times with flat out high winds. Explain any signs to tell you of a tornado that may appear. If any, explain a time that you remember going through, or seeing a tornado. This could include the sight of a funnel cloud or being close to where one hit.
