Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.

Why does Magma tends to rise toward the Earth's surface?
Magma rises from the asthenosphere to the surface of the Earth. After it reaches temperature upward to 1000 degrees Fahrenheit, the magma starts to rise. Gases also aid in pushing the magma toward the surface, along with the tremendous pressure from the depth at which it originates.
Magma tends to rise toward Earth's surface principally because?
Magma tends to rise towards Earth's surface primarily because rocks become less dense when they melt. The hotter the magma, the more the rocks are likely to "float," if you will.
Magma that reaches the Earth's surface is called what?
Magma that reaches the surface is referred to as lava.magma that has reached the earth's surface tends to cool faster, that is why the rock will have more holes in it than a rock that has not reached the earth's surface. magma that has cooled enough to become a rock is known as a igneous rock. but there are two types of igneous rock. ther is intrusive igneous and extrusive igneous. intrusive is when the magma has cooled on the inside. this rock will have large crystals because it has cooled slower and most likely it will have a fine grained texture. extrusive igneous is when magma has reached earths surface (thats when it becomes lava) and has cooled. these rock with either have very small microscopic crystals or no crystals at all because the lava cools so quickly that they do not have enough time to really form.
Ice tends to form at the?
Surface of bodies of water.
Why are people unevenly distributed on the earths surface?
Because some areas are much harder to live in: too cold, too hot, too dry, too wet, not fit to raise food on. The population tends to gather where it's easier to grow food and find water and other resources that they need. Please look at this answer and try to understand the meaning. Your teacher may ask you to put it in your own words.

Why do partly molten materials rise toward earths surface?
Magma is molten or partially molten rock beneath the earth's surface and is lighter than the surrounding rock so it tends to rise. As it moves upward, the magma encounters colder rock and begins to cool.

Which is the most abundant in magma and has the greatest effect on its characteristics?
Felsic magma tends to be thick and viscous, while mafic magma tends to be fluid.
What is the magma that reaches the earth's surface?
Magma that reaches the surface is referred to as lava.magma that has reached the earth's surface tends to cool faster, that is why the rock will have more holes in it than a rock that has not reached the earth's surface. magma that has cooled enough to become a rock is known as a igneous rock. but there are two types of igneous rock. ther is intrusive igneous and extrusive igneous. intrusive is when the magma has cooled on the inside. this rock will have large crystals because it has cooled slower and most likely it will have a fine grained texture. extrusive igneous is when magma has reached earths surface (thats when it becomes lava) and has cooled. these rock with either have very small microscopic crystals or no crystals at all because the lava cools so quickly that they do not have enough time to really form.

How does magma go into a volcano?
Being a less dense liquid, it rises toward the surface, seeking the path of least resistance. The volcano is simply a structure created by the rising magma and the surface features of its lava.
Why do magma and silca rich magma erupt explosively?
silica is a rich compound consisting of silicon and oxygen and tends to be thicker and is more resistant to flow. other lava with less silica flows easily so the amount of water vapor and other gases trapped in lava influences how lava erupts.
What effect does dust and dirt have on earths radiation?
They tends to block incoming solar radiation, thereby cooling the surface. They don't really impact Earth's longwave radiation.
What type of magma that tends to cause explosive eruptions has a what?
High temperature
What happens when Magma with a large amount of dissolved gases tends to be?
very explosive.
