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.
What else can I help you with?
Magma tends to rise toward earths surface?
Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.
Magma tends to rise toward Earth's surface principally because?
Magma rises towards Earth's surface primarily due to its lower density compared to the surrounding rock, causing it to be buoyant. Additionally, magma is forced upwards by the pressure created by the heat and gases trapped within the Earth. The movement of magma is also influenced by tectonic forces and the presence of fractures or faults in the Earth's crust.
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.
WHAT ARE THE THREE TYPES OF MAGMA AND THE DIFFERENCES?
The three types of magma are basaltic, andesitic, and rhyolitic. They differ in their silica content, viscosity, and eruptive behavior. Basaltic magma has low silica content, low viscosity, and tends to erupt quietly, while rhyolitic magma has high silica content, high viscosity, and tends to erupt explosively. Andesitic magma falls in between these two in terms of composition and behavior.
What mineral that affects magma thickness?
The mineral that affects magma thickness is silica. Magma with high silica content tends to be more viscous, resulting in thicker magma. Conversely, magma with low silica content is less viscous and flows more easily.
Magma tends to rise toward earths surface?
Yes, magma tends to rise towards the earth's surface. It does so because once melted it becomes less dense.
Why do some partly molten material rise toward Earth's 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.

Is cool magma sinking and warm magma convection?
Yes, cool magma tends to sink due to its higher density compared to warmer magma, which rises due to its lower density. This movement leads to convection currents in the magma chambers beneath the Earth's surface.
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.
Which is the most abundant in magma and has the greatest effect on its characteristics?
Silica is the most abundant component in magma and has the greatest effect on its characteristics. The amount of silica present determines the magma's viscosity, which in turn influences the explosiveness of volcanic eruptions.
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?
Magma that tends to cause explosive eruptions is typically high in silica content, making it thick and viscous. This results in gas build-up and pressure within the magma chamber, leading to explosive eruptions.
