Select all of the answers that apply. four laws or principles are involved with the study of stratigraphy. they are 1 law of original horizontality 2 law of superposition law of original lateral continuity 3 law of gravity and oppositional force 4 law of cross-cutting relationships

Four laws or principles are involved with the study of stratigraphy. They are law of original horizontality, law of superposition law of original lateral continuity, and law of cross-cutting relationships.

Answers that apply: 1, 2, and 4 or the first, second, and fourth option.

Option (1), (2) and (4) are the correct

Explanation:

According to the Steno, the four laws that deals with the study of stratigraphy are as follows-  

Law of Superposition- this law states that in a geochronological sequence the rock layers that are present at the top are the youngest and the rock layers that lies at the bottom are the oldestLaw of Original horizontally- this law states that the sediments usually gets deposited in a horizontal manner due to the influence of gravityLaw of Cross-cutting relationship- this law states that in a particular area when the igneous bodies (such as batholith, plutons etc) intrudes other rocks, then these intruding features are generally younger than the rocks which it cuts, maintaining a cross-cutting relationshipLaw of lateral continuity- this law states that the the sediments at first are deposited and extended laterally in every direction until they meet another geological feature that interrupts its path of lateral extension

The answer would be sand and gravel
