Across
- 3. a fundamental, constant property of matter representing the total "stuff" or material within an object, typically measured in kilograms (kg)
- 4. the amount of mass per unit volume of a substance
- 5. non-renewable, naturally occurring inorganic materials (metals, non-metals, and fossil fuels) concentrated in the Earth's crust in sufficient quantity to be extracted for economic or technological value
- 6. is a continuous, underwater mountain system formed by plate tectonics at divergent plate boundaries.
- 7. areas with higher-than-average temperatures, intense activity, or specific concentrations
- 8. a mathematical comparison of two quantities (numbers, measurements, or amounts) showing how many times one value contains or relates to another.
- 9. is the geological method of determining the chronological order of rocks, fossils, or events—identifying which are older or younger—without determining their specific numerical age in years
- 11. fundamental geological process at convergent plate boundaries where one tectonic plate, typically denser oceanic lithosphere, bends and slides beneath another, lighter plate into the Earth’s mantle
Down
- 1. a characteristic of matter that can be observed, measured, or detected by senses (sight, touch, smell) without altering the substance's chemical identity or composition.
- 2. natural materials or phenomena that can be harnessed to produce heat, power, electricity, or motion
- 10. the measure of the 3D space an object or substance occupies, typically measured in cubic units
