Why are metamorphic rocks very hard and resistant to wear?
quartzite is made from quartz. in the case of metamorphic rocks, quartzite is made from regional metamorphism. in the process of regional metamorphism, pressure is applied making the rock hard and dense.
Difference between intra and inter regional transportation?
international means between two or more countries. Inter-regional means between two or more regions, where a region can be a part of a country (for example, the Pacific North West), or a collection of countries (for example, Northern Europe).
What is the difference between regional climate and global climate?
Regional climate refers to the average weather patterns in a specific area over a long period of time. On the other hand, global climate encompasses the overall patterns of temperature, precipitation, and other weather elements across the entire Earth. Regional climate may vary significantly within a larger global climate system.

Difference in a charge between two electrodes in a cell causes a ----between electrodes?
Potential difference.
Difference between regional and local metamorphism?
Regional metamorphism occurs over a large area and at high pressures and temperatures, typically associated with tectonic processes like mountain building. Local metamorphism, on the other hand, is confined to a small area and occurs at lower pressures and temperatures, often as a result of contact with a heat source like a magma intrusion.
What is the difference between regional and contact metamorphism?
Regional metamorphism is the creation of metamorphic rock from large geographically significant processes like plate tectonics. Contact metamorphism is the creation of metamorphic rock from the proximity of an existing rock to a heat source provided by a plutonic intrusion.
What is the difference between regional and contact metamorphose?
Contact metamorphism is a type of metamorphismwhere rock minerals and texture are changed, mainly by heat, due to contact with magma.
What is the difference between contact and regional metamorphisim?
Contact metamorphism occurs when rocks are subjected to high temperatures and pressures due to proximity to a heat source, typically a magma intrusion. Regional metamorphism, on the other hand, is caused by widespread tectonic forces affecting large areas of rock, resulting in higher pressures and temperatures at deeper levels. Contact metamorphism is localized around the heat source, while regional metamorphism affects larger regions due to tectonic forces.
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 is the difference between contact and metamorphism?
Contact metamorphism is metamorphism that happens when preexisting rock comes in contact with a molten rock or magma and it melts locally.Regional metamorphism is metamorphism happens when two plates collide the plate that subducts can melt by the heated area.
When rocks stack up on each other what type of metamorphism can occur?
When rocks stack up on each other, regional metamorphism can occur. This type of metamorphism is caused by high pressure and temperature deep within the Earth's crust, typically associated with tectonic activity like mountain building or collisions between tectonic plates. This process can lead to the formation of new minerals and textures in the rocks.
Why are metamorphic rocks formed by contact metamorphism usually not as dense as those formed by regional metamorphism?
Contact metamorphism does not cause profound compaction, which is the reduction in size of the spaces between mineral particles due to increases in pressure. Regional metamorphism causes compaction and possibly recrystallization, increasing the density of the rock.
What is inter-regional planning?
state the difference between inter and intra regional planning development
What are the differences between a municipality and a town council?
Difference between Regional & Town Councillor and a town councillor?
What type of metamorphism did shale go through to become slate?
To metamorphose shale into slate you require a regional metamorphic environment which reaches temperatures of between 400-600oC and pressures of between 3-4 Kilo-bars (a burial depth of about 18 Km). The name of this sort of metamorphism is 'greenschist facies' with a 'Barovian' mechanism.
