The two major textures of metamorphic rocks are foliated and non-foliated. Foliated metamorphic rocks, such as schist and gneiss, exhibit a layered or banded appearance due to the alignment of minerals under directed pressure. Non-foliated metamorphic rocks, like marble and quartzite, do not display this layering; instead, they typically have a more uniform texture and are formed under conditions where pressure is applied equally in all directions.

What are 2 textures of metamorphic rock?
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.
What is 2 types of metamorphic rocks?
Metamorphic rocks are formed by the process of extreme heat, pressure and other chemicals. Two types of metamorphism are dynamic which makes the pressure and extreme heat and thermal which is caused by the heat of magma from a volcanic eruption.
What are two ways that can poduce metamorphic rocks?
Two ways in which metamorphic rocks are 1) contact metamorphism (thermal) where magma comes in direct contact with surrounding igneous rock and changes it due to high temperatures and usually low pressure. 2) Regional metamorphism (dynamothermal) ,high pressures and low temperature eg mountain ranges. or 3) Cataclastic metamorphism, heat as a result of friction due to two plate meeting or passing each other.
What 2 ways you can use metamorphic rocks?
Metamorphic rocks can be used as building materials for structures like countertops and flooring. They can also be used in the production of sculptures and carvings due to their unique colors and textures.
What are the 2 driving forces of metamorphism?
Heat and pressure.

What 2 things must increase for metamorphism to occur?
For metamorphism of rock to occur temperature and pressure must increase. Rocks created in this manner are called metamorphic rocks.

What are 2 examples of non foliated rocks?
Two examples of non-foliated rocks are marble, which forms from the metamorphism of limestone, and quartzite, which forms from the metamorphism of sandstone. These rocks do not have a layered or banded appearance like foliated rocks such as schist or gneiss.
What 2 things are metamorphic rocks formed from?
Heat and pressure are the most common cause of metamorphism of rock.
Would contact metamorphism or regional metamorphism be a product of 2 plates colliding?
Regional metamorphism would be the product of two plates colliding. The intense pressure and temperature generated during plate collision can create regional metamorphism, which affects a larger area and involves the recrystallization of rocks. Contact metamorphism, on the other hand, is caused by heat from a nearby magma intrusion and affects rocks in a localized area.
What is the difference between thermal metamorphism and regional metamorphism?
Thermal metamorphism is a type of metamorphism that occurs due to the heat from a nearby igneous intrusion, leading to changes in the mineralogy and texture of rocks. Regional metamorphism, on the other hand, is caused by high pressure and temperature over a large area, typically associated with tectonic plate collision or subduction. The main difference lies in the scale and mechanism of metamorphic changes, with thermal metamorphism being more localized and regional metamorphism affecting larger regions.

What 2 rocks are composed primarily of quartz feldspar and clay minerals?
Granite and gneiss are two rocks composed primarily of quartz, feldspar, and clay minerals. These rocks are commonly found in continental crust and are formed through the process of metamorphism or granitic magmatism.
Explain 2 ways Igneous Rocks Form?
Igneous rocks form when magma cools and solidifies either underground (intrusive rocks) or on the Earth's surface (extrusive rocks). Intrusive rocks cool slowly, allowing large crystals to form, while extrusive rocks cool quickly, resulting in tiny crystals or glassy textures.
