4. A mining company uses technology to study rock deep in Earth. They find evidence of an igneous rock formation underneath Earth's outer layer. Is it possible that material from this rock formation could ever form sedimentary rock on Earth's surface? No, sedimentary rock forms at Earth's surface because energy from the sun causes rock to weather, but igneous rock under Earth's outer layer is not exposed to energy from the sun. No, sedimentary rock can only form out of material from other sedimentary rock. There is no way that sedimentary rock can form from material in igneous rock. Yes, if igneous rock is moved to Earth's surface and exposed to energy from the sun, it could weather into small rock pieces that could form sedimentary rock. Yes, energy from Earth's interior can cause igneous rock to break into small rock pieces that can form sedimentary rock.
