Most Surface Rocks on Earth Are Younger Than a Few

question 270

Multiple Choice

Most surface rocks on Earth are younger than a few million years old, whereas ages of lunar rocks have been measured in billions of years. Why?

• A) Much of Earth's surface is continually recycled (created and subducted) by the underlying mantle because of plate tectonic activity; this process does not occur on the Moon.
• B) Most early surface rocks on Earth have been washed into the sea by weathering and rainwater; this process does not happen on the Moon.
• C) The complete surface of Earth has been covered periodically by younger material from intense volcanic eruptions in the last few million years; no such activity occurred on the Moon.
• D) The ages of Earth and the Moon are fundamentally different; the Moon is an old object captured from space by a younger Earth.
