,1. Multiple Choice: Which layer of the Earth is composed
primarily of iron and nickel?
a) Crust
b) Mantle
c) Outer core
d) Inner core
Answer: d) Inner core
Rationale: The inner core is the deepest layer of the Earth and is
composed primarily of iron and nickel, which gives it a solid
metallic state despite the high temperatures.

4. Multiple Response: Select all that apply. Which of the following
are types of plate boundaries?
a) Convergent
b) Divergent
c) Transform
d) Subductive
Answers: a) Convergent, b) Divergent, c) Transform
Rationale: Convergent, divergent, and transform are the three
main types of plate boundaries where tectonic plates interact with
each other. 'Subductive' is not a recognized type of plate boundary.


5. Multiple Choice: What is the primary cause of seasonal changes
on Earth?
a) The Earth's distance from the Sun
b) The tilt of the Earth's axis
c) The Earth's orbital shape
d) The Sun's temperature fluctuations
Answer: b) The tilt of the Earth's axis
