What else can I help you with?
What is the type of rock that comprises the bulk of the continents?
The type of rock that comprises the bulk of the continents is called granite. Granite is an igneous rock that is formed from the slow cooling of magma beneath the Earth's surface. It is a common rock found in continental crust.
Does granite rock sink or float?
Granite rock is denser than water, so it will sink when placed in water.
What is the name of a very porous igneous rock that is light it float?
Pumice is an example of this
Which igneous rock has tiny air bubbles trapped inside which allow it to float in water?
Pumice has tiny air pockets to help it float in water.
Is limestone heavier than granite?
No, granite is usually heavier than limestone. Granite is a denser and more compact rock, composed mainly of quartz, feldspar, and mica, while limestone is a sedimentary rock primarily made of calcite.
Does obsidian rock float?
No, obsidian rock does not float as it is a dense and heavy igneous rock formed from cooled lava. Its high density causes it to sink in water.
Can rocks float?
Pumice floats in water, but for other rocks you'd need to find a fluid that's more dense than the rocks to float them in. For example, mercury is almost 6 times as dense as granite, so a lump or slab of granite will ride right up there high in a pool of mercury.
What are the techtonic plates made of?
The Earth's tectonic plates are primarily made of solid rock, composed mostly of silicate minerals such as feldspar and quartz. These plates are rigid sections of the Earth's lithosphere that float on the semi-fluid asthenosphere beneath them.
Do igneous rocks float?
Most igneous rocks are denser than water, so they do not float. However, some types of igneous rocks, such as pumice, can contain trapped air bubbles which make them less dense than water, causing them to float.
How do you fix a float that is stuck?
The float could be stuck because of stuck needle valve, or rust. The float could also be leaking and be full of fuel.
How could you separate wood chips and pieces of granite rock?
Burn the wood chips. Alternatively, shake them around for a little while, the granite is heavier and would settle to the bottom, so you could remove the wood from the top, this isn't 100% effective, but it's more effective than setting it on fire. This can be accomplished by shoveling the mixture into water (a wheelbarrow, a buck, some other large container). The chips float and can be skimmed off. The granite sinks and can be shoveled out later.
DO ALL Igneous rocks sink?
No, pumice, a frothy lava containing pockets of air or gasses, is often very light and will float on water.
