Question

An earthquake is 1. (predictable, unpredictable). When an earthquake

occurs, the vibrations spread out in 2. (all, one) direction/s from its center.
The vibrations are most strongly felt at the 3. (epicenter, outer) and gradually
diminish as they spread out. Earthquakes happen when the 4. (oceanic,
tectonic) plates rub against each other, which makes the crust of the Earth
shake. The energy from the 5. (oceanic, seismic) waves is so strong that it
makes the crust of the Earth rumble, creating an earthquake.
Volcanoes are formed when 6. (cold, hot) molten rock or 7. (coal,
magma) deep underground oozes up to the surface of the Earth. They are
also formed as one of the plates is pushed under the other as it is heated to
a point where it begins to 8. (freeze, melt). When 9. (high, low) pressure
develops underground, the magma shoots up or erupts through a weak spot
in the Earth's crust. When the magma reaches the surface of the Earth, it is
called 10. (lahar, lava).

9. High

10. Lava

Step-by-step explanation:

An earthquake is unpredictable. When an earthquake occurs, the vibrations spread out in all directions from its center. The vibrations are most strongly felt at the epicenter and gradually diminish as they spread out. Earthquakes happen when the tectonic plates rub against each other, which makes the crust of the Earth shake. The energy from the seismic waves is so strong that it makes the crust of the Earth rumble, creating an earthquake. Volcanoes are formed when hot molten rock or magma deep underground oozes up to the surface of the Earth. They are also formed as one of the plates is pushed under the other as it is heated to a point where it begins to melt When high pressure

develops underground, the magma shoots up or erupts through a weak spot in the Earth's crust. When the magma reaches the surface of the Earth, it is called lava.
