it has been washed into the oceans as the continental crust has eroded.
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
The earth's crust is not stress
continental crust
formation rate of the ocean crust
Type your answer here... D.Comparing the composition of the crust to other bodies in the solar system

While soil composition is an important tool for understanding the earth's history, it alone cannot determine the age of the earth. Scientists use a variety of methods such as radiometric dating of rocks, fossils, and ice cores to determine the age of the earth. These methods provide more accurate and reliable information about the age of our planet.
Scientists study seismic waves to learn about the temperature inside the Earth's crust. By analyzing the speed and direction of these waves as they travel through different layers of the Earth, scientists can infer information about the temperature and composition of the Earth's crust.
The Earths crust is approximately 650 km deep.
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
mantle
The mantle is composed of basaltic rock, the crust is composed mostly of granitic rock. Basalt is denser than Granite.
The earth's crust is not stress
Scientists study movements in Earth's crust using techniques such as GPS monitoring, seismology, and satellite imagery. By analyzing data collected from these methods, scientists can track tectonic plate movement, earthquake activity, and volcanic eruptions to better understand the dynamics of the Earth's crust.
