xenn [34]

answer:

: D.finding fossils in the same area that are in layers closer to the surface.

Relative dating refers to the age estimation method in which past events are determined, to compare the age of object, organism, strata or rock with the age of other similar entity. This method gives an approximate or estimated age, it does not provide absolute age.  

The older fossils are found in deeper layers of the strata as compared to younger fossils. This represents the geological time and life span of primitive or preexisting organisms. Therefore, according to the given situation, finding fossils in the same area that are in layers closer to the surface is the best conclusion

The Earth is more massive than the moon. How will a person’s weight on the moon compare to their weight on Earth?
Rom4ik [11]

Answer:

The weight of a person on the moon is less, compared to their weight on Earth.

Explanation:

Gravitation is a force. Gravity is the force that tries to pull two objects toward each other.

Anything which has mass, also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. So because the moon iless massive than the earth, you will experience a less gravitational pull and therefore a you will experience less weight on the moon compared to your weight on earth.

EXTRA

The Gravitational pull is difined by the force that arises of masses of two objects in relation to their distance.

Earth's gravity is what keeps you on the ground and what causes objects to fall back to earth.

You can experience a change in gravitational pull on earth yourself, in an exelerating or decelerating elevator.
