earthquakes and landslides.
A volcano is...
a mountain built from magma.
What type of igneous rock form above the Earth's surface?
Extrusive igneous rock.
Subduction zone is...
where the less dense plates slides under the more dense plate.
Science is the...
system of aquiring knowledge through systematic experiment.
A fault is...
break in the Earth's crust.
A volcano is located...
near tectonic plates.
What are three types of non-foliated rocks?
Marble,soapstone,and quartzite.
The lithosphere is how thick?

1.0-10.0
A composite volcano is...
a volcano built up of alternating layers of rock paticles and lava.
What are the two types of changed rocks and define them?
They are non-foliated and foliated.Non-foliated do not have distinct layers or bands.Foliated have visible layers and elongated grains of minerals.
Blocks of the crust slide past each other along...
Fault lines.
This method helps scientists do experiments.
The scientific method.
Earthquakes which occur on ocean floor produces...
Tsunamis.
Ash that falls to the ground can cause...
buildings to collapse,bury crops,damage engines,and can cause breathing problems.
