What is the difference between volcanism at a hotspot and volcanism at mid-ocean ridge?
At a hotspot, a plume of hot magma comes up through the mantle, causing vulcanism. At a mid-oceanic ridge, two plates move away from eachother, leaving space that is filled by magma.
Hotspots and mid-oceanic ridges can exist together at the same place, Iceland being a prime example of this. However, Hawaii, which is also a hotspot place, is nowhere near plate boundaries, so it's not a place where you would normally expect vulcanism.

Intraplate volcanism may be associated with what formation?
Intraplate volcanism may be associated with hotspots. These are areas where magma rises from deep within the mantle to the surface of the Earth, independent of tectonic plate boundaries. The Hawaiian Islands are a famous example of intraplate volcanism caused by a hotspot.
The formation of the hawaiian islands is an example of what?
The formation of the Hawaiian Islands is an example of hotspot volcanism. A hotspot is an area of volcanic activity located beneath the Earth's crust, which creates a chain of volcanic islands as the tectonic plate moves over the hotspot, resulting in a series of volcanic eruptions that build up the islands over time.
Does the island of Hawaii experience volcanism because it is located above the mid pacific ridge?
No. The Island of Hawaii is located above a Hot Spot on the floor of the Pacific Ocean. That is a place where a plume of lava breaks through the floor of the Pacific ocean and pushes up mountains. The Pacific Ocean has other such Hot Spots. None are a big as that underneath the big island of Hawaii.
What causes volcanism?
Volcanism is primarily caused by the movement of tectonic plates, allowing magma to rise to the surface and erupt. This can happen at subduction zones, mid-ocean ridges, and hotspot locations. Other factors like pressure and temperature within the Earth's mantle can also influence volcanic activity.
What is a hot spot in relation to volcanoes?
This is a point in the Earth's crust where hot upwellijng mantle material causes significant magma formation and melting to occur within the crust and upper mantle. This in turn causes hotspot volcanism at the surface.
The island of Hawaii experiences volcanism because it is located above the Mid-Pacific?
False! The island of Hawaii experiences volcanism because it is located above a hotspot in the Earth's mantle.
What are the differences between ocean ridge and seamount?
The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.
What is the difference between hotspot and Wi-Fi?

What are hotspots?
Hotspots are portions of the Earth's surface that experience significant volcanism thought to be due to mantle plumes. They are normally located at a distance from plate boundaries where the majority of volcanism occurs.An example of a hotspot would be that underlying Hawaii and is responsible for the volcanism there and the creation of the Hawaiian island chain.
Intraplate volcanism may be associated with what formation?
Intraplate volcanism may be associated with hotspots. These are areas where magma rises from deep within the mantle to the surface of the Earth, independent of tectonic plate boundaries. The Hawaiian Islands are a famous example of intraplate volcanism caused by a hotspot.
Is an area where material from deep within the mantle rises and then melts forming magma?
This is known as a hotspot. Examples include the hotspot responsible for the Hawaiian Ridge-Emperor Seamounts chain and the one responsible for the significant volcanism of Iceland.
What is the difference between a hyperlink and hotspot?
Actually, there's not much difference. A hotspot is basically a "spot" on an image map and can be linked to whatever you want to link it to using a hyperlink. A hyperlink uses the notmal HTML link tags and can be a text or image link.
Where is the Rio Grande Rise?
The Rio Grande Rise is in the southwest Atlantic basin, at approx. 35 degrees W, 30 degrees south. It is the result of hotspot volcanism.
How was mtkilauea form?
Kilauea is formed by a hotspot.A hotspot is a location on the Earth's surface that has experienced active volcanism for a long period of time.Without Kilauea,the Hawaiian islands won't exist!
The formation of the hawaiian islands is an example of what?
The formation of the Hawaiian Islands is an example of hotspot volcanism. A hotspot is an area of volcanic activity located beneath the Earth's crust, which creates a chain of volcanic islands as the tectonic plate moves over the hotspot, resulting in a series of volcanic eruptions that build up the islands over time.
What is the difference between 'hotspot' and Wi-Fi?
WiFi-> Service Wireless-> Application With Wireless device we can conncet to Wireless internet With Wifi we can conncet to Wireless via AP or wireless router
What two plates formed the Mauna Kea?
Mauna Kea was formed primarily by the movement of the Pacific Plate over a hotspot in the Earth's mantle. As the Pacific Plate shifted northwestward, volcanic activity from the hotspot created the shield volcano that is Mauna Kea. The formation is not directly associated with the interaction of two tectonic plates, but rather the result of volcanism at a stationary hotspot beneath a moving plate.
