1. Which statement best summarizes the Law of Conservation of Matter?
- A. The total amount of matter is constant; it is only transformed.
- B. Matter can be converted into energy and destroyed during physical changes.
- C. Geological processes like weathering create new matter from nothing.
- D. The mass of an object decreases when its physical form is altered.
2. A large granite boulder with a mass of 500 kg is slowly broken down by weathering into smaller rocks and sand over many years. If you could collect every single particle from the original boulder, what would their total mass be?
- A. Exactly 500 kg
- B. Significantly less than 500 kg
- C. Significantly more than 500 kg
- D. It is impossible to predict the final mass.
3. A geologist observes a large mass of rock being melted into magma deep within the Earth. According to the principle of matter conservation, what happens to the matter that made up the original rock?
- A. It is converted into heat and energy.
- B. It is destroyed by the intense pressure.
- C. It changes its physical state but is not lost.
- D. It combines with other elements to create entirely new matter.
4. A student breaks a 10 kg rock and carefully collects the pieces, which then weigh 9.9 kg on a scale. What is the best scientific explanation for the missing 0.1 kg?
- A. Breaking the rock destroyed a small amount of its mass.
- B. The Law of Conservation of Matter does not apply to this type of change.
- C. Some rock was likely lost as fine dust that was not collected.
- D. The force of the break converted some mass directly into energy.
5. According to the Law of Conservation of Matter, when a mountain weathers away, what ultimately happens to the matter that composed it?
- A. It is permanently destroyed.
- B. It is converted into energy.
- C. It is relocated and changed in form.
- D. Its total mass significantly decreases.
6. A geologist observes a large granite outcrop that has been broken down into sand and smaller rock fragments over many years. Which energy source is the primary driver of this process?
- A. Geothermal energy
- B. Solar energy
- C. Kinetic energy from earthquakes
- D. Chemical energy from volcanic gases
7. When rock is pushed deep into the Earth and exposed to the intense heat of the planet's interior, what transformation is most likely to occur?
- A. It will be weathered into fine sediment.
- B. It will rapidly cool and crystallize.
- C. It will melt and become magma.
- D. It will be compacted into sedimentary rock.
8. Which of the following statements best describes the rock cycle as a system of matter and energy?
- A. It is a one-way process where rock is continuously destroyed.
- B. It is a system where matter is cycled and transformed by the input and transfer of energy.
- C. It is a static system where rocks remain unchanged for millions of years without any energy input.
- D. It is a chemical process that occurs entirely without the influence of external energy sources.
9. If a large mountain range is slowly worn down over millions of years, resulting in vast plains of sand and soil, which process and energy source are responsible?
- A. Melting, driven by geothermal energy
- B. Weathering and erosion, driven by solar energy
- C. Crystallization, driven by chemical energy
- D. Metamorphism, driven by Earth's interior energy
10. What is the fundamental principle that drives all the changes and transformations observed in the rock cycle?
- A. The constant pressure from gravity
- B. The continuous flow and movement of water
- C. The flow of energy through Earth's materials
- D. The slow passage of geological time
