Final answer:
As you go deeper into the Earth, both temperature and pressure increase due to the heat from the Earth's core and the weight of rocks above. option b is correct
Step-by-step explanation:
The correct answer to the question of how temperature and pressure change the further inside Earth you go is option B. temperature & pressure increase. As you go deeper into the Earth, the temperature increases due to the heat from the Earth's core and radioactive decay of elements. At the same time, the pressure also increases because of the weight of the rocks and materials above.
When heat adds energy to a system such as a confined gas, the general response is an increase in both pressure and volume if the volume is not confined, according to gas laws. However, inside the Earth where materials cannot freely expand, the increase in temperature will still drive up the pressure despite volume being restricted by the surrounding rock. option b is correct
