As it moves upward, the magma encounters colder rock and begins to cool. If the temperature of the magma drops low enough, the magma will crystallize underground to form rock; rock that forms in this way is called intrusive, or plutonic igneous rock, as the magma has formed by intruding the surrounding rocks. If the crust through which the magma passes is sufficiently shallow, warm, or fractured, and if the magma is sufficiently hot and fluid, the magma will erupt at the surface of the earth, possibly forming volcanoes. Magma that erupts is called lava. For more information go to: http://encarta.msn.com/encyclopedia_761595520/Magma.html

Why does coffee cool down faster in a saucer than a cup?
because the interracial porportions in the cup are virtually stronger in the cup, but the saucer has more optical durability, so the coffe sees the saucer and goes, "dang that saucer be pim ping" but it is too much for the coffe to handle, therefor the coffee cools down quicker than in the cup
Does sand or air cool faster?
Sand usually cools faster than air because sand has a higher thermal conductivity, meaning it can transfer heat more efficiently than air. This enables the sand to lose heat more quickly to its surroundings compared to air.
Why does water cool down quicker in a tray with a larger surface area?
Water cools down quicker in a tray with a larger surface area because there is more area for heat exchange with the surrounding air. The increased surface area allows more water molecules to come into contact with the cooler air, facilitating faster heat transfer and cooling.
Which heats and cools faster?
An object with low heat capacity heats and cools faster than an object with high heat capacity. Objects with low heat capacity require less energy to raise or lower their temperature compared to objects with high heat capacity, which means they heat up or cool down faster.
Does water or sand cool faster after dark?
Sand cools faster after dark than water because sand has a lower specific heat capacity compared to water. This means that sand stores less heat energy and can release it more quickly than water when exposed to cooler temperatures.
Lava is magma that has reached the what in an eruption?
Lava is magma that has reached the surface of the earth in an eruption. When this cools down, it will form igneous rocks.
Does water cool more quickly than land?
Land cools faster because land is floating on the earths surface. Water gets deeper, so the suns heat cant heat the bottom of the ocean as well as the surface
Is lava magma when it cools down?
No. Lava is magma that has reached the surface.
How does the shape surface area and volume affect how fast magma cools?
The shape affects the ratio of surface area to volume. The greater the surface are to volume ratio, the faster the magma will cool.
Can you give two reason why pouring a cup of hot coffee into a saucer results in faster cooling?
If you pour it in a saucer, it will spread out and there is less surface area and it cools faster.
What type of soda cools faster?
coke it has less sodium and sugar then other sodas an when it has less it cools faster
Is it faster to cool beverages in ice only or ice water?
ice water, cause the cold temperature is touching more of the bottle or cans surface area so it cools down faster
When air cools to a temperature the air has reached what?
When air cools to a temperature where it can no longer hold all of its water vapor, the air has reached its dew point. This is when condensation occurs, forming clouds or fog.
What type of breezes occur because land cools off faster than water?
Land breeze occurs when the land cools off faster than the water, causing air to move from the land towards the water. This usually occurs at night.
When magma cools earth's surface what type of crystalline structure is usually found?
When magma cools on the Earth's surface, it usually forms an aphanitic crystalline structure. This means that the crystals are very fine-grained and not easily visible to the naked eye. Examples of rocks with this type of structure include basalt and rhyolite.
Why can you sip hot tea from a saucer faster than from a cup?
If you pour it in a saucer, it will spread out and there is less surface area and it cools faster.
When air cools to a temperature at which is saturated the air has reached its?
dew point
