Question

Nicolaus steno set down two geologic principles. what are they

Answer 1

Nicolaus Steno was a Danish geologist who gave two geological principles.
1. Principle of Original Horizontality - This principle states that sediments are deposited in the form of horizontal layers under the action of gravity.
2. Principle of Lateral Continuity - It states that the layers of sediments are deposited laterally in all directions in a continuous manner over the Earth's surface.

Answer 2

Nicolaus Steno set down two geologic principles, they are:
1. Principle of original horizontality: it states that layers of sediments are originally deposited horizontally under the force of gravity.
2. Principle of lateral continuity: it states that layers of sediments initially extend laterally in all directions.
These two principles are important in the analysis of folded and tilted strata.
