What is metamorphic rocks with a non-foliated texture show metamorphic change that involves?
Lesson 5: Metamorphic RocksScience 7 A Unit 2: Earth's Materials1. All of the following conditions in Earth can cause metamorphic rocks to form except _____. (1 point)(1 pt) exposure to air(0 pts) the presence of hot, watery fluids(0 pts) heat(0 pts) pressure1 /1 point2.Metamorphic rocks that show layers of dark minerals alternating with layers of light minerals are classified as _____.

(1 point)(0 pts) mineral grains arranging into layers(1 pt) growth in the size of the mineral grains(0 pts) mineral grains flattening under pressure(0 pts) mineral grains melting1 /1 point
Expansion and contraction with regard to weathering are caused by rusting.?
Expansion and contraction in materials due to rusting occur when iron in the material reacts with oxygen in the presence of water, forming iron oxide (rust) which has a larger volume than iron. This expansion and contraction can lead to cracking and weakening of the material over time.
Why the mineral of a metamorphic rock usually different from the protolith?
Remineralization can occur because of an exchange of fluids or because the squeezing out of fluids by pressure and heat create an environment where hydrous minerals cannot exist and are replaced with non-hydrous minerals.
What physical change in metamorphic rock signals the end of metamorphism?
from what i know there is no physical change that signals the end of metamorphism but there is a physical change during the process of metamorphism. during metamorphism the shape of the rock changes due to force of stress this is a physical change. (a physical change is when the shape or composition ofa substance e.g. rock has changed). by the way i am only 12
What soil is produce more fertile soil igneous or metamorphic?
Igneous soil tends to be more fertile than metamorphic soil because it contains minerals like potassium, phosphorus, and magnesium that are beneficial for plant growth. Metamorphic soil undergoes high heat and pressure, which can decrease its fertility by altering the mineral composition and reducing nutrient availability for plants.
Which forces allow for mineral growth and change within metamorphic rocks?
It is heat and pressure.
Basalt can change into what metamorphic rock?
When basalt undergoes metamorphism, it can change into a metamorphic rock called greenstone. Greenstone is a fine-grained metamorphic rock that forms from the alteration of basalt through metamorphic processes like recrystallization and the growth of new minerals.

A regional metamorphic belt is divided into zones based upon?
A regional metamorphic belt is divided into zones based upon the intensity of metamorphism, with different mineral assemblages and textures characterizing each zone. This zoning reflects the temperature and pressure conditions experienced during metamorphism, with higher grade zones typically exhibiting more extensive recrystallization and mineral growth compared to lower grade zones. Additionally, the presence of index minerals can help geologists identify the specific metamorphic zone within a region.
What soil is produce more fertile soil igneous or metamorphic?
Igneous soil tends to be more fertile than metamorphic soil because it contains minerals like potassium, phosphorus, and magnesium that are beneficial for plant growth. Metamorphic soil undergoes high heat and pressure, which can decrease its fertility by altering the mineral composition and reducing nutrient availability for plants.
How does temperature increase cause metamorphism?
Temperature increase causes metamorphism by increasing the kinetic energy of mineral atoms, leading to recrystallization and growth of new minerals. This process can result in the development of foliation, new textures, and changes in mineral composition, transforming the rock into a metamorphic rock.
When a sedimentary rock changes into a metamorphic rock what are the affects?
sedimentary rocks undergo metamorphism under certain heat and pressure to give the metamorphic rocks. the affect of this formation on environment is negligible as this frames the part of rock cycle. further these metamorphic rocks melts to form magma. magma further cools and solidify to form igneous rocks.
Describe how pressure acts as an agent of metamorphism?
Metamorphic rock is formed by intense heat and pressure. Pressure compresses and changes the composition and appearance of these types of rocks. For example, whether pressure is evenly applied or not determines if metamorphic rocks are foliated.
What is epitaxialiality?
. The growth of the crystals of one mineral on the crystal face of another mineral
