Answer: A. convergent
Most earthquakes occur at the boundary where two plates meet. This phenomena is called as convergent plate tectonics. In this phenomena the two plates moves towards each other. If the plates are of equal density then they will push each other but if they are of unequal density, the denser plate sink beneath the other plate.
One difference is that some animals are polyp and some are medusa.
The other difference is that some animals have medusa in their life or polp in their life cycle.
Hope these two differences helps :D
Answer:
Pillow basalt is a volcanic igneous rock that forms when lava of basaltic compositionis erupted underwater. The rapid cooling of the lava by cold water on all sides forms the pillow-shaped bodies, which can then break open and extrude more of the hot lava from inside.
To find joules (heat) we use the following formula
heat= mass x specific heat x ΔT
mass= 72.5 grams
specific heat (Water)= 4.184 j/g·C
ΔT= 95 - 28= 67 °C
heat= (72.5 grams) (4.18 j/g·C) (67°C)= 20300 joules or 20.3 Kilojoules
