Question

question 24(multiple choice worth 3 points)
(03.02 lc)
which layer of earths mantle is the hottest?
asthenosphere
atmosphere (not a part of mantle)
lithosphere
mesosphere

question 25(multiple choice worth 3 points)
(03.03 lc)
what type of plate boundary interactions take place when tectonic plates
convergent boundaries
divergent boundaries
subduction boundaries
transform boundaries

Explanation:

For Question 24:

• The Earth's mantle has layers. The mesosphere is deeper within the mantle compared to the asthenosphere and lithosphere. As we go deeper in the Earth (in the mantle region), temperature generally increases. The atmosphere is not part of the mantle.

For Question 25:

• Subduction boundaries are a type of convergent boundary interaction. But subduction specifically occurs when one tectonic plate is forced under another. Convergent boundaries involve plates moving towards each other, divergent plates move apart, and transform plates slide past each other. Subduction is a key process in plate - boundary interactions where one plate is “subducted” (goes beneath) another.

Answer:

Question 24: Mesosphere
Question 25: Subduction boundaries
