What else can I help you with?
What can you infer about metamorphic rocks from their names?
That they have undergone some form of change. For more information on metamorphic rocks please see the related question.
What two types of rocks make up the lithosphere?
The lithosphere is primarily made up of two types of rocks: igneous and metamorphic rocks. Igneous rocks form from the cooling and solidification of magma, while metamorphic rocks are rocks that have undergone a change in texture and composition due to heat and pressure.
What three rocks form when rocks bend?
When rocks bend, they can form folds, such as anticlines, synclines, and monoclines. These folds are structures caused by the pressure and movement within the Earth's crust, resulting in the bending and deformation of rocks.
What can form when a compression squeezes rocks at a convergent place boundary?
Mountains
What deformational structures results in brittle deformation?
Brittle deformation results in structures like fractures, fault gouge, and breccia. These structures form when rocks break or fracture due to stress without significant plastic deformation. They are commonly found in highly stressed and brittle rocks near the Earth's surface.

How do natural rocks structures form?
by heat and pressure
What do deposited weathered rocks form?
Deposited weathered rocks can form sedimentary rocks through processes like compaction and cementation. These rocks are made up of fragments of pre-existing rocks that have undergone weathering and erosion before ultimately being deposited and lithified to form a new rock.
How are cracks in rocks at right angles to the surface?
Cracks in rocks at right angles to the surface are typically the result of tensile stresses acting on the rock. These stresses can be caused by factors such as cooling and contraction, unloading and expansion, or tectonic forces. As the rock experiences these stresses, cracks form perpendicular to the direction of the stress, resulting in fractures that are often at right angles to the surface.
What branch of science studies metamorphosis?
Metamorphosis means 'change in form' and is undergone by some animals, which comes under biology (specifically zoology). It is also a process undergone by rocks, which is geology.
What are rocks that have grains that lie in a pattern of flat layers or form swirls?
Rocks with grains that lie in flat layers are sedimentary rocks, which include sandstone and shale. Rocks with swirling patterns are often metamorphic rocks, such as gneiss or marble, which have undergone intense heat and pressure causing their minerals to align in distinct patterns.
How can igneous sedimentary and metamorphic rocks form?
igneous rocks form when hot molten rock cools and solidifiessedimentary rocks form when other rocks erode and the erosion products collect then are buried and fuse together or minerals are deposited by living things and are buriedmetamorphic rocks form when other rocks are buried deep and the high temperature and pressure removes volatiles and modifies crystal structures in the rock
What two types of rocks make up the lithosphere?
The lithosphere is primarily made up of two types of rocks: igneous and metamorphic rocks. Igneous rocks form from the cooling and solidification of magma, while metamorphic rocks are rocks that have undergone a change in texture and composition due to heat and pressure.
These rocks form from previously existing rocks that have been altered by heat and pressure?
These rocks are metamorphic rocks. They form when existing rocks (igneous, sedimentary, or other metamorphic rocks) undergo high temperatures and pressure deep within the Earth's crust, causing their minerals to recrystallize and new minerals to form. Metamorphic rocks can have distinct textures and structures depending on the intensity of the heat and pressure they experienced.
What three rocks form when rocks bend?
When rocks bend, they can form folds, such as anticlines, synclines, and monoclines. These folds are structures caused by the pressure and movement within the Earth's crust, resulting in the bending and deformation of rocks.
Compressional stresses can form what?
compressed stress
Why the study of rocks are important to civil engineers?
Studying rocks is important for civil engineers because rocks form the foundation of many structures. Understanding the characteristics and behavior of rocks helps engineers determine the feasibility and design of construction projects such as tunnels, dams, and bridges. Knowledge of rock properties is crucial for ensuring the stability and safety of these structures.
