What is a hardened layer in a volcano?
As lava cools, it hardens and forms a thick layer of rock. These rocks are known as igneous rocks. An example of an igneous rock is pumice, which is used in spa treatments to soften feet.
What would you find under Kaibab limestone if you were to drill a hole into the Kaibab limestone?
Layer after layer of sedimentary rock, then eventually metamorphic and igneous rock. The layer directly underneath the Kaibab is the Toroweap Formation, a layer of darker limestone.
What type of rock forms when molten rock cools?
Rock that forms from molten rock that cools and solidifies is called igneous rock.
Type of rock formed from molten rock?
Igneous rock is formed when magma cools and becomes solid.
What kind of rock is formed after a volcano erupts?
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
How does the age of a rock layer compare with an igneous intrusion that is through it or an igneous rock extrusion above it?
If it is above it, the rock layer came after the intrusion. if the intrusion went through the rock layer is older because they layer had to be there in order for the intrusion to go through.
Why do rock fossils form in sedimentary rock and not in igneous rock?
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
What layer of the earth is composed of igneous metamorphic and sedimentary rock?
The crust.
How would igneous rock be on a layer of sedimentary rock?
The igneous rock could have been erupted as lava on the surface, or intruded into the sedimentary rock layers as magma underneath the surface (a sill).
What causes igneous rocks to become sedimentary rocks?
If other layers of rock, dirt, dust, and sand are put on top of the igneous rock and the layers are compressed by their own weight, they become a single, unified layer of sedimentary rock. Simple Version: 1. Igneous rock 2. More rocks are put on the igneous rock. 3. The rock on top push down and squeeze the all of the layers into one layer.
What is a hardened layer in a volcano?

What layer of the earth is thin chemically complex?
The thinnest layer of the earth is the outer layer, or the crust. It is made up of sedimentary, metamorphic and igneous rock.
What would you find under Kaibab limestone if you were to drill a hole into the Kaibab limestone?
Layer after layer of sedimentary rock, then eventually metamorphic and igneous rock. The layer directly underneath the Kaibab is the Toroweap Formation, a layer of darker limestone.
What forms when lava flows horizontally across a layer of rock?
Forms of igneous rock are usually made. It is also known as lava rock and volcanic rock
How can igneous rock disturb sedimentary rock layers?
Igneous rocks can disturb sedimentary rock layers and formations by their movement during ascent through such layer. when they make contact with this sedimentary rocks they could result to folding and/or metamorphism.
What type of rock forms when molten rock cools?
Rock that forms from molten rock that cools and solidifies is called igneous rock.
What describes rock that was formed when molten rock cooled down?
Igneous rock is formed.
