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.

Mr. j, age 42, is a construction worker in las vegas. he recently noticed that a mole on his face seemed to be getting larger and darker. at first he did not worry because he was in the sun a lot and assumed the change may have been caused by sunburn. after a month, not only was the mole larger and darker, but it appeared to be “bumpy.” his doctor diagnosed a malignant melanoma skin cancer following biopsy of the nevus. mr. j reports pain in his right shin that does not go away when he puts his feet up or sleeps. discussion questions 1. relate mr. j’s skin changes to the warning signs for malignant melanoma. (see malignant melanoma.) 2. discuss the normal progression of this malignancy. what is the significance of the bone pain that mr. j is experiencing? (see malignant melanoma.) 3. discuss the treatment available for this patient and the prognosis for recovery. (see malignant melanoma.)
