What is weathering?
The process of breaking down rock by natural means

Why do sand dunes most likely form by an ocean
Water and wind can both move sand. Sand dunes form where the wind is strong and the sand deposits are plentiful. That is why the beach is the perfect location for them!

What are two phenomenon that can be both destructive and constructive depending on the situation?
Earthquakes and volcanoes
500
How do earthquakes happen?
The earth's plates collide on the fault lines
