The lithosphere primarily comprises of volcanic rocks and sediments that contain fluids and water. These fluids contact the rocks surrounding as the lithosphere moves into the mantle in the downward direction. The rock's melting temperature decreases when the fluid begins the enter the hot rock. This melts it to form magma.
Adding fluids to hot rock can lower the melting point of the rock minerals, essentially triggering melting and leading to the formation of magma. The fluids facilitate the movement of atoms within the rock, allowing them to rearrange and melt. This process, known as flux melting, is common in subduction zones where water-rich fluids are released from the subducting slab, promoting magma formation.
When the fluids enter the already hot mantle rock, the melting temperature of the hot rock decreases. As a result, the rock begins to melt.
hot rock melts and the hot fluid builds up to make an explosion which makes magma

What makes Ripple marks in sandstone may form by heat action of?
Ripple marks in sandstone can form due to the heat action of hot fluids or gases moving through the sedimentary layers. This process can cause the sand grains to align in a ripple pattern as the sediment is compacted and cemented into rock over time.
Does all magma come from the earths core?
No, not all magma comes from the Earth's core. Magma can also originate from the mantle, which is the layer beneath the Earth's crust. The heat and pressure from the mantle can cause rocks to melt and form magma, which can then rise to the surface as volcanic eruptions.
Describe the factors that might cause magma to form a laccolith instead of a sill?
A laccolith forms when magma is injected into a horizontal crack in the rock layers, causing the overlying rock to arch upwards. This is influenced by factors such as the viscosity of the magma, the amount of pressure exerted, and the density contrast between the magma and surrounding rock. If the magma is less fluid and exerts greater pressure, it is more likely to form a laccolith instead of a sill, which forms when magma intrudes parallel to the rock layers.
Why is lava and magma not a rock?
Lava and magma are not rocks because they are liquids and cant harden because they are to hot to harden and cant cool themselves down long enough to form a hard structure. Magma and lava is rock - it's just been superheated by the Earth's core.
Does sedimentary rock form from the cooling of magma?
No. Igneous rock forms from the cooling of magma.
What causes magma to form at a convergant plate?
the mid ocean ridges cause the magma to form at a convergent plate boundary.
What causes magma to form at convergent boundaries?
the mid ocean ridges cause the magma to form at a convergent plate boundary.
What causes magma to form at a convergent boundary?
the mid ocean ridges cause the magma to form at a convergent plate boundary.
Explain how the additional of fluids to hot rock causes magma to form?
The lithosphere primarily comprises of volcanic rocks and sediments that contain fluids and water. These fluids contact the rocks surrounding as the lithosphere moves into the mantle in the downward direction. The rock's melting temperature decreases when the fluid begins the enter the hot rock. This melts it to form magma.
What causes Magma to form a convergent plate boundary?
the mid ocean ridges cause the magma to form at a convergent plate boundary.
How do deposition form?
Most hydrothermal deposits form from hot, metal-rich fluids that are left during the late stages of the movement and cooling of magma.
How do hydrothermal deposit form?
Most hydrothermal deposits form from hot, metal-rich fluids that are left during the late stages of the movement and cooling of magma.
What are the main things that cause rocks to form?
the main things that cause metamorphic rocks to form is heat, pressure and chemical fluids.
What are the main things that cause metamorphic rocks to form?
the main things that cause metamorphic rocks to form is heat, pressure and chemical fluids.
How deep in the earth can magma form?
Magma can form at varying depths in the Earth, typically from about 30 kilometers to over 150 kilometers beneath the surface. The exact depth at which magma forms depends on several factors, including the composition of the mantle rocks and the presence of fluids or volatiles that can lower the melting point of rocks.
What cause rocks to form?
Igneous rock is formed from the cooling and solidification of magma or lava.
How do vein minerals form?
Vein minerals are those that form in fissures in the existing rock, either thru deposition by mineral saturated hydrothermal fluids, or injection of magma and subsequent cooling.
