Question
A theory: •
• Occurs with unvarying uniformity under ideal conditions. •
• Explains why events occur in nature. •
• Does not have to have the agreement of the scientific community. •
• Asks a question that needs to be answered. •
• Is the result of one single well-proven and well accepted-hypothesis.
2 . What energy source is Earth using primarily for its internal processes? •
• Primordial heat from Earth’s formation •
• The core •
• Radioactive decay •
• The sun
3. Solar energy is the primary energy source for earthquakes.
• True
• False
4. The water cycle on our planet is driven primarily by Earth’s:
• Internal processes
• External processes
5. The layer that encompasses an entire tectonic plate is called: •
• Asthenosphere •
• Crust •
• Mesosphere •
• Lithosphere •
• Outer Core
6. The outer layer of the Earth defined by its composition is called: •
• Crust •
• Mesosphere •
• Asthenosphere •
• Lithosphere •
• Outer core
7. The core of the Earth is composed primarily of:
• Hydrogen •
• Oxygen •
• Silicon •
• Iron/Nickel •
• Uranium
8. The lithosphere and the crust are identical layers. There is no difference between them at all.
• True
• False
9. What type of plate boundary is located here in the San Francisco Bay Area? •

• Passive margin •
• Earthquake margin •
• Tectonic margin
14. Ocean trenches: •
• Are caused by divergence at divergent margins. •
• Parallel continents and island arc volcanoes. •
• Are created at transform boundaries during earthquakes. •
• Are typically only ~10 meters deep.
15. The portion of the continental margin that marks the true edge of the continent is: •
• Continental shelf •
• Continental slope •
• Continental rise •
• Abyssal plain
16. Submarine canyons are believed to be shaped primarily by: •
• Transform faults •
• Rifting •
• Turbidity currents •
• Converging ocean plates
these are multiple choices.Please answer all the questions.
Explanation / Answer
Question 1) answer) option E)
Reason : A theory Is the result of one single well-proven and well accepted-hypothesis
Question 2) answer) option c) radioactive decay
Reason : internal processes inside earth due to radioactive decay links the core, the mantle and the crust creating a dynamic system
Question 3) false
Reason : the primary energy source for earthquakes is the elastic energy stored in bent rock
Question 4) answer) external processes
Reason : water cycle is very important for the living beings on the earth which plays a major role in ground water , rains etc
Question 5) Answer) lithosphere
Reason : lithosphere comprises of the broken segments knows as Tectonic plates , whose movement results in the earthquakes
Question 7 ) iron nickel
Reason : Earth's core is mainly composed of iron nickel alloy
