Why is evaporation a cooling process? Give a scientific reason. How does an igneous rock turn into a metamorphic rock? What evidence do we have for the movement of tectonic plates? Explain how we know that tectonic plates move. How does "global positioning system" (GPS) technology work? Wha...
How does the viscosity of magma change as magma cools? What kinds of geologic features form at subduction zones? How does a sedimentary rock become an igneous rock? How was the Kilauea volcano created? Explore our homework questions and answers library ...
Hornfels is a fine-grainedmetamorphic rock that was subjected to the heat of contact metamorphism at a shallow depth. It was "baked" by heat conducted from a nearby magma chamber, sill, dike, or lava flow. ... This specimen of hornfels is thought to have formed with sandstones and silts...
The kids will love learning about the science of rocks with thisdelicious rock cyclemade of chocolate rocks. Chocolate shavings become sedimentary, igneous, and metamorphic types of rocks in this easy-to-follow science experiment. I’ve included a printable rock cycle diagram perfect for classrooms ...
How does foliation occur in metamorphic rocks? Foliated Metamorphic Rocks: Foliation formswhen pressure squeezes the flat or elongate minerals within a rock so they become aligned. These rocks develop a platy or sheet-like structure that reflects the direction that pressure was applied. ...
During the formation of a maar, the rock above the magma chamber is usually blasted away. This suddenly reduces the confining pressure on the magma and its dissolved gas. The sudden pressure reduction allows an immediate and violent expansion of the dissolved gas. The magma then degasses like ...
Cinder cones form when molten rock known as "magma" approaches Earth's surface. The magma that forms cinder cones contains a tremendous amount of dissolved gas - and that gas is what powers a cinder cone eruption. Some gas-charged magmas contain several percent volcanic gas on the basis of ...
Question: How do fossil fuels form in sedimentary rock? Fossil Fuels: Fossil fuels are possible fuel sources that are carbon-based, such as petroleum and natural gas. These are considered nonrenewable resources, as they take millions of years to form. ...
It's pretty easy to give a hot stone massage at home, but it does take some preparation. First, you'll need to get stones, either...
How is basalt formed? In what ways can magma be generated from solid rock? How do volcanoes affect the lithosphere? How does the Earth's core influence plate tectonics? How many minerals are found in the Earth's crust? How hot is the oceanic crust? How are metamorphic rocks formed?Explore...
