Metamorphic activity is most common along what type of plate boundaries?

What is the angular deviation of a fault or tilted bed called or measured as?

Trace fossils indicate organic activity, like tracks or trails.

Metamorphic rocks may form from:

Horizon C, the lowest layer in a soil column, has the highest organic content.

Plastic strain occurs when deformed rocks break or fracture as brittle solids.

Punctuated equilibrium is the gradual accumulation of minor changes eventually resulting in the origin of a new species.​

Greenstone belts are some of the youngest rocks on Earth.​

A poorly-sorted sediment might consist of:

Strain is the deformation caused by forces applied to a given area of rock (stress).
