True or false 1. The upper mantle is also known as the mesosphere
2. Earthquakes can be found at both transform and convergent boundaries. However, at
convergent boundaries, the earthquakes are the strongest.

false and true is the correct answer

1: false

2:true

Explanation:

number one is false because the upper mantle is known as asthenosphere.

number two is true because at convergent plate boundaries, where two continental plates collide earthquakes are deep and also very powerful. In general, the deepest and the most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.

think about the oscillation of the toy shown in the video. when the toy is at the highest point of its motion, its velocity is zero and its acceleration is negative.

real, smaller and upside-down.   so the answer should be b.
