Pillow basalts are indicators that the lava was erupted where?
Pillow basalts are indicators that the lava was erupted underwater or in a marine environment. The cooling process of these lavas forms characteristic pillow-shaped structures as they interact with the water.
What kind of rock forms when lava cools in the ocean?
When lava cools in the ocean, it forms a type of rock called pillow basalt. This distinctive rock gets its name from its pillow-like shape that results from the rapid cooling of lava in water. Pillow basalt is commonly found in areas where underwater volcanic eruptions occur.
When Lava cools underwater what usually forms?
When lava cools underwater, it usually forms a type of igneous rock known as pillow lava. This occurs because the rapid cooling of lava in water causes it to solidify quickly and take on a rounded, pillow-like shape. Pillow lava formations are commonly found at mid-ocean ridges and undersea volcanoes.
Are Basaltic lavas are generally hotter and more viscous than andesite lavas?
No, basaltic lavas are typically hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which results in their lower viscosity and ability to flow more easily. Andesite lavas, on the other hand, have higher silica content and are more viscous.
Are Basaltic lavas generally hotter and more viscous than andesite lavas?
Basaltic lavas are generally hotter and less viscous than andesite lavas. Basaltic lavas have lower silica content, which makes them flow more easily. Andesite lavas, on the other hand, have higher silica content, making them cooler and more viscous.

What is the closest to the center of a spreading axis on the sea floor carbonate ooze silceous pillow lavas or turbidites?
Some thing that ha an ending too it self.

What are the pillow lavas in new zealand?
Pillow lava are eruptions of volcanic material underwater, and consequently their rapid quenching causes them to form discrete 'pillow' shapes. Commonly 500 to 1000 mm in size. Notable are those at Red Rocks on Wellington's south coast, and at Boatman's harbour in Oamaru. No doubt many other areas as well.
What is associated with a teenage girls sleepover?
Pillow fights. I think.

Why are the Crystal's in pillow basalt smaller than those of in other example of basalt?
Pillow basalts are lavas that were erupted and cooled in sea water. Therefore, they have had very little time to form crystals of any size, during rapid solidification, when compared to most land or air-born eruptions.
What are some geology key terms?
dyke - verticall lava through a rock. sill - horizontall lava through a rock. pillow lavas - pillows sold in asda which support your gullable head as you sleep.
What is the difference between the way intrusive and extrusive igneous is formed?
Intrusive igneous rocks cool beneath the crustal surface. Extrusive cool above the surface - pillow lavas cool below the sea but above the crust.
How do rhyolitic magma or lava and basaltic lava differ?
rhyolitic mama is associated with explosive volcanism and is ejected (blown out of) a volcano rapidly. Basaltic lavas are released during effusive volcanism that is not explosive, such as hawaii where the lave "flows" into the ocean slowly. Basaltic lavas have a lower silica content as well.
