$100 Question from H1 The least dense and solid portion of the Earth
$100 Answer from H1 What is the crust?
$200 Question from H1 The partially liquid middle layer of the Earth. Like the white part of an egg.
$200 Answer from H1 What is the mantle?
$300 Question from H1 This part contains the crust and upper part of the mantle.
$300 Answer from H1 What is the lithosphere?
$400 Question from H1 These two layers are made from the mantle. The first is liquid like and the second is more solid.
$400 Answer from H1 What is the asthenosphere and mesosphere? (Must be in that order)
$500 Question from H1 Describe the core, both parts. (This answer is not in the traditional Jeopardy format.)
$500 Answer from H1 They are the densest parts of the Earth. The outer core is liquid and the inner core is solid and mostly made out of iron.
$100 Question from H2 These are extremely fine pieces of rock that are made in explosive volcanic eruptions.
$100 Answer from H2 What is ash?
$200 Question from H2 These are types of pyroclastic materials that are made when magma cools in the air.
$200 Answer from H2 What are lapilli and volcanic bombs?
$300 Question from H2 These are large chunks of the mountainside that are blown away from the site in an eruption.
$300 Answer from H2 What are volcanic blocks?
$400 Question from H2 This type of lava forms underwater.
$400 Answer from H2 What is pillow lava?
$500 Question from H2 Ouch! This type of lava is sharp and jagged.
$500 Answer from H2 What is Aa?
$100 Question from H3 What occurs when two plates collide.
$100 Answer from H3 What is a convergent boundary?
$200 Question from H3 When an oceanic plate collides with a continental plate, this process occurs and this reason.
$200 Answer from H3 What is subduction because the oceanic plate is more dense?
$300 Question from H3 The major type of this boundary exists near California and causes major earthquakes to happen there.
$300 Answer from H3 What is a transform boundary?
$400 Question from H3 Seafloor spreading and midocean ridges occur at this type of boundary.
$400 Answer from H3 What is a divergent boundary?
$500 Question from H3 This type of boundary is creating the Himalayan Mountains. Be specific.
$500 Answer from H3 What is a continental-continental convergent boundary?
$100 Question from H4 At one point all the continents formed one land mass called this.
$100 Answer from H4 What is Pangaea?
$200 Question from H4 After Pangaea began to split apart, two large continents were formed.
$200 Answer from H4 What are Gondwana and Laurasia?
$300 Question from H4 This is how seafloor spreading creates continental drift.
$300 Answer from H4 What is by adding new crust at a midocean ridge and pushing the old crust further away.
$400 Question from H4 Continental drift also explains what curiosity about some fossils in the southern hemisphere.
$400 Answer from H4 What is how the same fossil plants and animals can appear on continents that are separated by thousands of miles of ocean?
$500 Question from H4 Another piece of evidence for seafloor spreading and continental drift.
$500 Answer from H4 What is the magnetic reversals in rock on the ocean floor?
$100 Question from H5 In its last eruption, Mt. St. Helens went through what kind of eruption?
$100 Answer from H5 What is explosive?
$200 Question from H5 These types of eruptions are the most common and occur where in the world.
$200 Answer from H5 What is nonexplosive and at midocean ridges?
$300 Question from H5 What two chemicals will make a magma more explosive?
$300 Answer from H5 What is water and silicon?
$400 Question from H5 This type of eruption occurred most recently at Yellowstone and this type of eruption of the Yellowstone volcano has been the most destructive.
$400 Answer from H5 What is nonexplosive and explosive? (Must be in that order.)
$500 Question from H5 Magma can make an eruption be explosive by doing what two things.
