  • Lava Plateaus
  • Calderas
  • Soil from lava and ash
2 circle the letter of each sentence that is true about shield volcanoes
2. Circle the letter of each sentence that is true about shield volcanoes.
  • They form from many thin layers of lava.
  • They result from quiet eruptions.
  • They are very steep mountains.
  • They are formed from ash, cinders, and bombs.

TRUE

is the following true or false some types of volcanic activity do not involve the eruption of lava
Geothermal ActivityIs the following true or false? Some types of volcanic activity do not involve the eruption of lava.

TRUE

slide17
When groundwater heated by a nearby body of magma rises to the surface and collects in a natural pool, it is called a(n) ____________.

19. A fountain of water and steam that erupts from the ground is referred to as a(n) ____________.

hot spring

geyser

how can geothermal energy be converted to electricity
How can geothermal energy be converted to electricity?

Steam from underground is piped into turbines. Inside a turbine, the steam spins a wheel. The moving wheel in the turbine turns a generator that changes the energy of motion into electrical energy.
