Not all minerals form perfect visible crystal shapes. Some crystals are too small to see. What are the 6 crystal forms of minerals? The six crystal families are triclinic, monoclinic, orthorhombic,

Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest. What are tectonic plates GCSE? Tectonic plates are
Why does it rain after earthquake?
Regional SpecificsWhat happens to the surface after an earthquake? Earthquakes often cause dramatic changes at Earth’s surface. In addition to the ground movements, other surface effects include changes in the flow of groundwater, landslides, and mudflows. Earthquakes can do significant damage to buildings, bridges, pipelines, railways, embankments, dams, and other structures. Do earthquakes start underwater? A
