Metamorphic Rocks form from existing rocks that have been heated and squeezed?
Yes, a metamorphic rocks is an existing rock that has been transformed via heat and pressure.
Water released from deep-sea vents has been heated by?
hot rocks deep in the crust.
What is the major difference between igneous and metamorphic rocks?
igneous rocks started as melted lava and cooled to be rocks. Metamorphic rock started as a sedimentary rock, and was heated up and put under pressure to create the metamorphic rock. Classic example - igneous = obsidian. Metamorphic = marble (marble is limestone that's been heated and squeezed a lot).
Why is lava a liquid?
Because it contains rocks/minerals that have been heated to their melting point, inside the earth.
What would be considered a rock?
A rock consists of lots of minerals, which are made up of elements such as gold and silver. A rock can contain valuable minerals such as diamonds. Diamonds are the most expensive minerals. You can mine rocks and minerals at a mine
What kind of metamorphic rock is formed where rocks have been heated but not deformed?
A metamorphic rock formed where rocks have been heated but not deformed is called a contact metamorphic rock. This type of rock forms when existing rocks are altered by the heat from nearby magma without experiencing significant pressure or deformation. Examples include hornfels and marble.
A sedimentary rock that forms when rock fragments are squeezed together is called a what kind of rock?
A sedimentary rock that forms when rock fragments are squeezed together is called a conglomerate. This rock is composed of rounded fragments that have been cemented together by a finer material, such as sand or mud.
What are rock fragments that are squeezed together?
Rock fragments that are squeezed together tightly form a sedimentary rock called breccia. Breccia is composed of angular fragments of rocks that are cemented together by a fine-grained matrix. It typically forms near fault zones or where there has been significant rockfall or landslides.
Is it true that clastic rocks form when a rock fragment are squeezed together?
Yes, clastic rocks form from the accumulation and lithification of rock fragments (clasts) that have been eroded and transported by water, wind, or ice. These clasts are typically cemented together under pressure to form sedimentary rocks such as sandstone, conglomerate, and shale.
What do you call a liquid that has been heated to a gas?
A liquid that has been heated to a gas is called vapor.
What is it called when the coils of a spring are spread out?
The spring has been stretched. When the coils are squeezed together then the spring has been compressed.
How do metamorphic rocks become metamorphic rocks?
A metamorphic rock is an igneous, sedimentary, or another metamorphic rock that has been: 1) squeezed by incredible pressures deep underground, 2) has been exposed to very hot fluids, 3) has been exposed to very high temperatures without melt occurring, 4) combinations of numbers 1-3. Rock exposed to these conditions can be metamorphosed, altering its structure, mineral alignment, and possibly its chemistry.
