Question

evidence suggests that earth is about 4.6 billion years old, even though no earth rocks have been found that can be dated at more than 4 billion years old. question using your knowledge of surface features, explain why we do not find many rocks 4 billion years or older on earth

Explanation:

Earth's surface features like plate tectonics, weathering, erosion, and volcanic activity constantly recycle and destroy rocks. Plate tectonics subducts old rocks into the mantle. Weathering and erosion break down rocks on the surface. Volcanic activity covers old rocks with new lava. These processes make it rare to find rocks 4 billion years or older.

Answer:

Earth's surface processes (plate tectonics, weathering, erosion, volcanic activity) recycle/destroy old rocks.
