Volcanic Landform S3
Section 3 Volcanic Landforms
| Question | Answer |
|---|---|
| Name 5 landforms from lava to ash | Shield Volcanoes, Cinder Cone Volcanoes, Composite Volcanoes, Lava Plateaus and Calderas |
| Shield Volcano | lava flows gradually build a wide, gently sloping mountain. Quiet eruptions |
| Cinder Cone | a steep, cone-shaped hill or mountain. Explosive eruptions |
| Composite Volcanoes | tall, cone-shaped mountains in which layers of lava alternate with layers of ash, cinders, and bombs. Both quiet and explosive eruptions |
| Lava Plateaus | thin, runny lava erupts from cracks in the ground hardens into layers |
| Calderas | the huge hole left by the collapse of a volcanic mountain |
| True or false: Volcanic soils are some of the richest soils on earth? | True |
| How does volcanic soil form? | It is the breakdown over years of the hard lava |
| What are features formed by magma include? | volcanic necks, dikes, sills, batholiths, dome mountains |
| Volcanic neck forms when... | magma hardens in a volcano's pipe |
| Magma that forces itself across rock layers hardens into a... | dike |
| Magma that squeezes between layers of rock it forms a ... | sill |
| A mass of rock formed when a large body of magma cools inside the crust is... | batholiths |
| This forms when rising magma is blocked by horizontal layers of rock... | dome mountains |
| What is the process that creates a lava plateau? | lava flows out of several long cracks in an area. Thin, runny lava flows far before cooling and becoming hard. |
| How does a dome mountain form out of magma that hardened beneath the surface? | the magma forces the layers of rock to bend upward into a dome shape. |
| What types of volcanoes would you find on Mars? | shield and cone-shaped volcanoes |
| What is Io? | a moon of the planet Jupiter |
| What is Triton? | a moon of planet Neptune |
| True or false: Io and Triton have volcanic features similar to Earth, Mars and Venus? | False |
| Lava on the surface creates landforms such as... | shield volcanoes, cinder cones, composite volcanoes, and plateaus |
| What is a benefit of volcanoe soil? | fertile soil |
| True or false: Venus and Mars both have active volcanoes? | False- they are extinct |
| Alternating layers of lava and volcanic ash are found in... | Composite volcanoes |
| Olympus Mons, the largest mountain in the solar system is found on what planet? | Mars |
