Yes
no they do not
No, most of the actinides do not occur naturally in Earth's crust. Actinides are a group of elements that are mostly synthetic or man-made through nuclear reactions. Only a few actinides, like uranium and thorium, occur naturally in significant quantities in the Earth's crust.
Uranium and thorium are the two actinides that occur naturally in the Earth's crust. They are found in low concentrations and have important roles in various nuclear reactions and processes.
Many minerals occur naturally on the earths surface in rock form
A mineral must occur in the Earth's crust, which is the outermost layer of the Earth. This layer extends from the surface down to about 50 kilometers deep. Minerals are typically formed through geological processes in the crust, making this layer the most common place to find them.
Most Faults Occur Where The Earths Crust Is Extended

No. Americium is a synthetic element. It does not occur naturally on earth.
most times earthquakes occur
They Can occur anywere a Fault Line is on Earth They happen when earths crust releases and the Fault Line send out Energy =p
The atmospheric layer closest to the Earth's crust is the troposphere. It is where we live and where most weather phenomena occur.
Sodium does occur naturally on Earth. It is a common element found in various minerals, soils, and water bodies. Sodium is also a key component of salt, which is abundant in the Earth's crust and oceans.
