Question

21 which of the following is the major cause of earths seasons?
(a) the position and distance of the earth in reference to the sun
(b) the coriolis effect
(c) the tilt of the earths axis of rotation
(d) the cycle of the moon in its revolution around earth

1. which type of plate boundary is associated with the creation of oceanic crust?

(a) convergent boundaries
(b) divergent boundaries
(c) transform boundaries
(d) collision boundaries

1. which type of plate boundary is associated with earthquakes?

(a) convergent boundaries
(b) divergent boundaries
(c) transform boundaries
(d) all of the above

1. which of the following is a direct result of a subduction zone?

(a) rift valleys
(b) oceanic trenches
(c) shield volcanoes
(d) continental shelves

Explanation:

• Question 21: The tilt of the Earth's axis of rotation causes the seasons. As the Earth orbits the Sun, different parts of the Earth receive different amounts of sunlight at different times of the year due to this tilt.
• Question 22: Divergent boundaries are where tectonic plates move apart. Magma rises from the mantle to fill the gap, creating new oceanic crust.
• Question 23: All types of plate boundaries (convergent, divergent, and transform) can be associated with earthquakes. At convergent boundaries, plates collide and can cause earthquakes; at divergent boundaries, as plates move apart, there can be seismic activity; and at transform boundaries, plates slide past each other, often causing earthquakes.
• Question 24: A subduction zone is where one tectonic plate is forced under another. This process creates oceanic trenches. Rift valleys are associated with divergent boundaries, shield volcanoes can be formed in various settings (not directly from subduction zones in the most straightforward sense), and continental shelves are part of the continental margin (not a direct result of subduction zones).

Answer:

1. C. The tilt of the Earth’s axis of rotation
2. B. Divergent Boundaries
