what are the three basic types of rocks

what do you call the STUDY of different layers of stratified rocks

which does not belong in the physical changes that are responsible for the fort-nation of rocks

• weathering

• deforming

• cooling

• eroding

• compacting

strata is presented in

• horizontal layers

• vertical layers

what do you call the PROCESS of creating layers of rocks

• strata

• stratified rocks

• stratification

• stratigraphy

there are how many classification of rocks

• 3

• 2

• 1

• 4

select the basic law of geochronology

• original horizontality

• lateral continuity

• superposition

• cross-cutting

which is the definition of law of superposition

• layers of sediments are deposited horizontally

• layers of rocks are continuous until they encounter other solid bodies

• any geological feature that cuts across, or disrupts another feature must be younger than the feature that is disrupted

• in any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on the bottom

in the law of original horizontality, the layers of sediments are deposited horizontally under the action of what

whcih law was proposed by Nicholas Steno

• superposition

• lateral continuity

• original horizontality

• cross-cutting
