Question

why is it hard to find the age of earth? (1 point)
○ earth’s surface is constantly changing.
○ there are too many layers of earth.
○ the earth is constantly moving.
○ there is no way to find the age of rocks.

Explanation:

To determine why it's hard to find Earth's age, we analyze each option:

• Option "Earth's surface is constantly changing": Erosion, plate tectonics, and other processes constantly reshape Earth's surface, destroying or altering old rock layers that could be used to date Earth. This makes it hard to find original, unaltered materials for age determination.
• Option "There are too many layers of Earth": The number of layers isn't the main reason; it's the alteration of layers, not just quantity.
• Option "The Earth is constantly moving": Earth's movement (like orbital or rotational) doesn't directly hinder age - dating of the planet's formation.
• Option "There is no way to find the age of rocks": Radiometric dating and other methods can determine rock ages, so this is false.

Answer:

A. Earth's surface is constantly changing.
