Igneous Rocks: Basalt and Granite
What else can I help you with?
Is tuff formed in the oceanic crust?
Tuff is generally formed from volcanic ash ejected during explosive volcanic eruptions. While some tuff deposits can be found in oceanic crust areas due to subduction zone volcanism, they are more commonly associated with volcanic activity on land.
What kind of landforms are formed from subduction?
Landforms formed from subduction include deep ocean trenches, volcanic arcs, and mountain ranges. Subduction occurs when one tectonic plate is forced beneath another, creating these distinctive features through processes such as volcanic activity and uplift.
What kind of rock types are found in hot spots?
Hot spots are known to produce basaltic rocks, such as basalt and rhyolite. These rocks are typically associated with volcanic activity and are formed from the cooling and solidification of magma from the Earth's mantle. The specific rock type found in hot spots can vary depending on the composition of the magma and the conditions of the eruption.
How are the three rock and types formed?
Igneous: These rocks are volcanic in nature. They are split into two categories in where they cool/crystallize: intrusive (internal) and extrusive (external). Intrusive volcanic rocks cool slowly, so they contain (usually) large crystals, like granites. Extrusive rocks are quite the opposite, in which they cool very quickly. This is where you get your obsidian glass and basalts. Sedimentary: These rocks are depositional and categorized by the kind of sediment it is made up of. Metamorphic: This can be the offspring rock of either a morphosed igneous or sedimentary rock. This metamorphism is accomplished by heat and/or pressure, and during a great length of time.

Volcanic activity creates what kind of rocks?
Volcanic activity produces extrusive igneous rock.
Which kind of rock is abundant in bicol region?
The Bicol region in the Philippines is abundant in volcanic rocks due to its location along the Pacific Ring of Fire, which is characterized by tectonic plate movements and volcanic activity. Common volcanic rocks found in Bicol include andesite, basalt, and tuff. These rocks are formed from the cooling and solidification of lava and ash erupted from volcanoes in the region.
What kind of mountain range is formed when rocks layers are squeezed and forced upward?
Volcanic Mountains Folded Mountains to be correct!
What kind of atoms is sand made up of?
Depends on the rocks which formed sand: silicon dioxide, calcium carbonate, volcanic minerals.
What kind of land form are the Mariana Islands and why?
The Mariana Islands are volcanic in origin. They were formed through the activity of underwater volcanoes in the Pacific Ocean. This volcanic activity created the islands' unique landform of rugged terrain and steep mountains.
What kind of minerals are the cascade mountains made up of?
The Cascade Mountains are primarily composed of volcanic rocks like basalt, andesite, and dacite. These rocks are the result of ancient volcanic activity in the region. Additionally, there are granite and other intrusive rocks present in some areas of the Cascades.
What kind of rocks did scientists in a submersible see when they observed the mid ocean ridge that help them realize that new material is being formed in the ocean?
It was lava (volcanic magma) from undersea volcanic vents.

What kind of rocks is formed in the ground?
Solid rocks
What kind of rocks are formed by in a river?
sedimentary rocks
Why do monutains have minarels?
Mountains have minerals because they are formed through various geological processes such as volcanic activity, sedimentation, and tectonic activity. These processes can bring minerals from deep within the Earth's crust to the surface and deposit them in the mountain rocks. Over time, weathering and erosion can also expose minerals in mountains.
What kind of rocks are in Death Valley?
Metamorphic, along with volcanic and plutonic igneous rocks.
