During the Pennsylvanian time period, there was a lot of volcanic activity and these constituted a lot of rock formation. Volcanic ashes also settled on the earth's surface and buried some trees.

Mesozoic era what events happend to begin and end this era?
The Mesozoic period began about 250 million years ago when the Permian-Triassic extinction occurred, probably by a combination of gradual atmosphere change and some external event like an Earth impact. The period ended about 66 million years ago with another great extinction, this one probably a combination of an impact and volcanic activity.
Explain the difference between the volcanic activity that occurs at a hot spot and the volcanic activity that occurs at a subduction boundary between an oceanic plate and a continental plate?
the second one is a result of the oceanic plate being pushed into the magma while the ring of fire is like how those crusts are formed by the lava reaching the surface then creating a mountain like structure then another one is made and the first one is pushed aside and erodes. Hawaii an example of this
An example of a caldera is?
It is a cauldron-like volcanic feature usually formed by the collapse of land fallowing a volcanic eruption.
What are volcanic blocks?
Volcanic Blocks are solid, irregularly shaped lumps of hardened lava, often large and boulder like in appearance; some rare volcanic blocks may weigh many tons!
What color is volcanic rock?
Volcanic rocks are usually dark grey to black in colour - however some (like pumice) may be light grey.
How did earth look like in the pennsylvanian period?
Warm and rainy. Mostly covered in coal forests.
Does Iceland have volcanic activity regularly?
Yes, Iceland has volcanic activity every five years or so on average. It's just mild activity and rarely is it anything like what Eyjafjallajokull has been.
What did the earth's surface look like during the Pennsylvanian period?
The first reptiles appeared in the Pennsylvanian Era/Period.
Essential life materials like nitrogen and carbon are exchanged and recycled through?
Volcanic activity.
What is volcanic fallout?
Basically it is a fallout but with high dangers of volcano activity EVERWHERE just like bombing with radiation and have to go to fine material that is volcanic proof to live
What happens if the moon stops going around the earth?
Tidal and tectonic activity will cease. Volcanic activity will increase and the earth will eventually look like Venus.
What happened during the Pennsylvanian period?
One is that the first reptiles (not dinosaurs!) appeared. The land during this peiod was swamp-forests.
What is vulcanism?
'Vulcanity' is also known as 'volcanism' or 'volcanic activity'. Examples of volcanic activity are: - Cracks or fractures appear - Gases like sulphur, hyrdrogen and carbon dioxide are detected - Pyroclast (like solidified lava)
What you the name of the volcano in Great Britain?
There isn't one!!! At least not any more, there used to be Volcanic activity in Great Britain as can be seen by volcanic plugs like Dumbarton Rock and Castle Rock in Edinburgh.
Which areas in the world contain the most igneous rock record?
Areas such as the mid-ocean ridges, volcanic arcs, and hotspots have extensive igneous rock records due to ongoing volcanic activity. Additionally, regions with ancient shield volcanoes, like the Canadian Shield and Fennoscandian Shield, also contain large amounts of igneous rocks from past volcanic activity.
Is made of sediments an igneous rock characteristics?
No, rocks made of sediments are called sedimentary rocks. Igneous rock comes from volcanic activity -- lava and the like.
Recent volcanic activity in different parts of the world supports the inference that volcanoes are located mainly?
along tectonic plate boundaries, where the movement and interaction of plates create conditions for magma to rise and erupt on the Earth's surface. This is known as plate tectonics theory, which explains how most volcanic activity occurs in specific regions like the Ring of Fire in the Pacific Ocean and the Mid-Atlantic Ridge. However, there are also some volcanic hotspots that occur away from plate boundaries, such as the Hawaiian Islands.
