Why it is difficult for scientists to locate the oldest rocks on Earth? (1 point)
IS
O Rocks are constantly eroded by weather.
• The oldest rocks can only be found at the Earth's inner core.
O Lava flow from volcanoes buries the old rocks.
O Rocks are broken down into smaller pieces over time.
Rocks are constantly eroded by weather.
The correct answer is: Rocks are constantly eroded by weather.
Scientists face difficulties in locating the oldest rocks on Earth because rocks are constantly eroded by weather. Weathering involves the breakdown and wearing away of rocks due to exposure to elements such as wind, water, and ice. This process over time can result in the destruction or alteration of older rocks, making it challenging for scientists to find rocks that have survived for billions of years. Erosion can remove layers of rock, exposing younger layers and obscuring the older ones. Additionally, erosion can transport rock fragments to other locations, making it difficult to piece together the geological history accurately.
