Geologists can determine the actual age of features on a planet by the radiometric dating method in which the age of the rocks is calculated by the natural decay of the radioactive isotopes of elements such as carbon.
In the radiometric dating method, the radioactive minerals in rocks are used. The radioactive isotopes, which are the chemical elements, naturally break down and decay to form a new isotope.
Each radioactive element has a unique decay rate which is known. Hence, the radioactive isotopes are crucial for the geologist to compare and identify the age of the rocks and furthermore, the planet.

Explanation:
Answer:
When the side of the earth that faces the moon experiences a high tide, the side of the earth that is opposite from the moon will have a<u> high tide.</u>
Explanation:
During the rotation of Earth , moon pulls the Earth , since it is close to Earth .
As moon pulls Earth , it also pulls the water in the oceans , and water can move quite easily and the ocean's water tries to bulge towards the direction of the moon . This process is known as tidal force .
Due to this tidal force , some portion of the ocean will bulge out , and this bulge is referred to as high tide.
.
Newton's 2nd law of motion says: <u>Force= (mass) x (acceleration)</u>
You know the force and the mass, and you need to find the acceleration.
So divide each side of the formula by (mass).
Then you have:
(force) / (mass) = acceleration .
Write the quantities that you know in their places,
and bada-bing, out falls the answer you need.
