Magma flows out of a weak spot in the Earth's crust due to the build-up of pressure from the molten rock beneath the surface. This pressure can result from the heat and movement of tectonic plates, creating pathways for magma to rise and eventually erupt onto the surface as lava.

What can erupt to bring a lava flow to earths surface?
magma
Why is continental crust deeper than oceanic crust?
The oceans flow to the places where the crust is the lowest. Gravity causes them to flow downward. The mantle, below the crust, is at the same depth everywhere, so if the crust is lower, it is because it is thinner.
What is the term for the flow of magma through cracks in the earth's surface?
The term for the flow of magma through cracks in the Earth's surface is called volcanic eruption. During an eruption, magma is forced through fissures or vents onto the surface, leading to the formation of volcanic features like lava flows, ash clouds, and pyroclastic flows.
What kind of volcano is formed when magma breaks through the crust?
A volcano formed when magma breaks through the Earth's crust is called a shield volcano. These volcanoes have gently sloping sides and form from the flow of low-viscosity lava.
How does valcano occur?
Volcanoes occur when there is a rupture in the Earth's crust, allowing magma to rise to the surface. This magma can erupt explosively or flow out more gently, forming different types of volcanoes. Volcanic activity is driven by the movement of tectonic plates and the melting of rock beneath the Earth's surface.
What causes magma to flow upward thought the earths surface?
The tectonic plates push together thus causing magma to shoot up and rise hence an eruption
What can erupt to bring a lava flow to earths surface?
magma
What is the force that move the Earth's plates?
The force that causes most of the plate movement is thermal convection, where heat from the earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the of plate the crust along with them.
What explains the movement of the earth's crust?
The earth's crust moves because the earth has tectonic plates that move because the magma under the earth's surface is constantly boiling. Since the water moves, it causes the earth's crust to move.
What causes surface ocean currents to flow in a circular pattern or earths revolution earths revolutoin or earths rotation?
Surface ocean currents flow in a circular pattern due to a combination of Earth's rotation (Coriolis effect) and the shape of the continents. The Coriolis effect causes water to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, resulting in the circular motion of currents. This, along with the shape of the coastlines, influences the direction and pattern of ocean currents.
What natural phenomenom occurs when magma breaks through the earth crust?
A lava flow may flow over the surface from a fissure deep enough to reach the magma layer. Or, if under pressure, an eruption from a volcano.
Why is continental crust deeper than oceanic crust?
The oceans flow to the places where the crust is the lowest. Gravity causes them to flow downward. The mantle, below the crust, is at the same depth everywhere, so if the crust is lower, it is because it is thinner.
What is the Flow of magma through the earths surface called?
I believe the answer you may be looking for is either Lava or a Volcano

How the movement of tectonic plates result in the formation of crustal features?
Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
How does valcano occur?
Volcanoes occur when there is a rupture in the Earth's crust, allowing magma to rise to the surface. This magma can erupt explosively or flow out more gently, forming different types of volcanoes. Volcanic activity is driven by the movement of tectonic plates and the melting of rock beneath the Earth's surface.
