Answer:

1. B

2. C

Step-by-step explanation:

1. Epicenter- The point on Earths surface directly above the focus of an earthquake.

   Focus- The focus is the place inside Earths crust where an earthquake originates.

   Intensity- The severity of earthquake shaking is assessed using a descriptive scale – the Modified Mercalli Intensity Scale

   Magnitude- Earthquake size is a quantitative measure of the size of the earthquake at its source. The Richter Magnitude Scale measures the amount of seismic energy released by an earthquake.

2. Nonexplosive eruptions- can release huge amounts of lava

   Explosive eruption- clouds of hot debris, ash and gas rapidly shoot out from a volcano. Instead of producing lava flows, explosive eruptions cause molten rock to be blown into tiny particles that harden in the are.

   Quiet eruption- lava erupts in a stream of low-viscosity lava, called a lava flow. Lava flows from a quiet eruption can travel for great distances.
