What type of lava forms a hot spot?
Hot spots typically produce basaltic lava, which is low in viscosity and allows it to flow easily. This type of lava arises from the mantle and is associated with volcanic activity that occurs away from tectonic plate boundaries. The Hawaiian Islands are a classic example of a hot spot, where magma rises through the Earth's crust, creating shield volcanoes characterized by gentle slopes formed from fluid lava flows.
How are the hawaiian volcanoes different to other volcanoes?
Hawaiian volcanoes are primarily shield volcanoes, characterized by their broad, gentle slopes and fluid basaltic lava flows, which result in non-explosive eruptions. Unlike stratovolcanoes, which can produce explosive eruptions due to their more viscous magma, Hawaiian eruptions tend to create lava fountains and lava lakes. This is largely due to the hot spot volcanic activity beneath the Pacific Plate, which allows for consistent, less viscous lava production. Additionally, the unique geological setting of Hawaii contributes to the formation of extensive volcanic islands rather than typical volcanic mountain ranges.
What are the four types of lava that form at hot spots and their characteristics?
Aa is lava that forms a thick ,brittle crust . Pahoehoe is a lava that forms a thin crust. Pillow lava forms when lava erupts underwater. Blocky lava is kool, stiff lava that does not travel far from thr eruption site.
Do oceanic crust hot spot volcanoes tend to erupt more explosively than other volcanoes?
No, oceanic crust hot spot volcanoes tend to erupt with less explosiveness compared to subduction zone volcanoes. The lava from hot spot volcanoes is typically less viscous, allowing gases to escape easily and reducing the likelihood of explosive eruptions.
Why are there different types volcanoes?
there are different types of volcanoes for different reasons. how they form has alot to do with the type of lava said volcano produces. fluid basaltic lava tends to create shield volcanoes. spatter cones tend to form when hot erupting lava contains just enough explosive gas to prevent the formation of a lava flow, but not enough to shatter it into small fragments. hot expanding gas tears the lava into hot fluid clots.
How is lava at divergent boundaries similar to lava at hot spot?
Yes.

What is that part of the earth that is relatively hot and that behaves as a highly viscous fluid?
The asthenosphere.
What processes forms most mountains?
lava ozzing out of a vent which is a hot spot
Is block lava the same as pyroclastic flow?
No. Block lava is low-moving viscous lava, usually of andesitic or similar composition. A pyroclastic flow is a very fast-moving mixture of hot ash, rock and gas.
What is lava like?
Lava is molten rock that flows out of a volcano during an eruption. It is extremely hot, ranging from 1,300 to 2,200 degrees Fahrenheit, and has a thick, sticky consistency that can vary from runny to more viscous depending on its composition. As it cools and solidifies, it forms different types of volcanic rock.

Can you really swim in lava?
No. There are 3 reasons.Lava is extremely hot, and falling in lava would result in certain death.Lava is dense, about the same density as rock, so you would not sink in far enough to swim.Lava is viscous, so ignoring the first two reasons, it would be like trying to swim in molasses with the most fluid lavas.
What is the hot liquid in the mantle called?
The hot liquid in the mantle is primarily referred to as magma, which is a molten rock material. While the mantle itself is mostly solid, it behaves like a viscous fluid over geological timescales, allowing for the movement of tectonic plates. When magma rises to the Earth's surface, it can erupt as lava during volcanic activity.
Which type of lava-basaltic lava or rhyolitic lava flows faster and why?
Basaltic flows much faster than rhyolite. Rhyolite is higher viscosity. Find a video of a basaltic lava flow like Hawaii, it flows like water when it's hot. Rhyolite eruptions usually act more like toothpaste if they're slow, or an explosion if fast.
