What is the system of cracks that form where the seafloor is spreading apart called?
The system of cracks that form where the seafloor is spreading apart is called a mid-ocean ridge. These cracks are also known as rift zones and are where magma rises to create new oceanic crust.
Does Magma push towards the Earth's surface through cracks?
Yes, magma pushes towards the Earth's surface through cracks in the crust, a process known as volcanic activity. When pressure builds up beneath the surface, magma can force its way through weak points in the crust, such as fractures or faults, leading to volcanic eruptions.
What does magma have to do with seafloor spreading?
When seafloor spreading occurs, it pushes the underground magma up though the new crust, creating a sort of volcano out of the new crust. Magma is a very important part in seafloor spreading. :]
What is you it called when volcanic activity occurs along mid-ocean ridge in large cracks?
Volcanic activity along mid-ocean ridges in large cracks is called seafloor spreading. This process occurs as magma rises to the surface through these cracks, creating new oceanic crust as the tectonic plates move apart.
Were does magma often move upward though in the crust?
Magma often moves upward through the Earth's crust along cracks and fractures in the rock, known as magma conduits. These conduits can be created by tectonic activity, such as the movement of tectonic plates, which can provide pathways for magma to reach the surface and form volcanic eruptions.
What happens to magma that rises though cracks on the seafloor?
When magma rises through cracks on the seafloor, it can result in the formation of underwater volcanic structures like mid-ocean ridges or seamounts. As the magma reaches the surface, it can solidify and create new oceanic crust through a process called seafloor spreading. Eruptions can also produce hydrothermal vents, which support unique ecosystems due to the extreme conditions.

The system of cracks that form where the seafloor is spreading apart is called a mid-ocean ridge. These cracks are also known as rift zones and are where magma rises to create new oceanic crust.
What is the process by which new crust is created when the seafloor moves apart and magma rises up?
This process is called seafloor spreading. It occurs at divergent plate boundaries where tectonic plates move apart. Magma rises up from the mantle through the cracks, solidifies upon contact with the cold seawater, and forms new oceanic crust.
Does Magma push towards the Earth's surface through cracks?
Yes, magma pushes towards the Earth's surface through cracks in the crust, a process known as volcanic activity. When pressure builds up beneath the surface, magma can force its way through weak points in the crust, such as fractures or faults, leading to volcanic eruptions.

When the seafloor spreads apart does hot saltwater move upward and flows from the cracks?
Yes, when the seafloor spreads apart, hot magma rises and creates new crust at mid-ocean ridges. This process can heat up seawater in the cracks, leading to hydrothermal vents where hot, mineral-rich water is ejected into the ocean.

Volcanic activity along mid-ocean ridges in large cracks is called seafloor spreading. This process occurs as magma rises to the surface through these cracks, creating new oceanic crust as the tectonic plates move apart.
What seafloor is the process by which new crust is created when seafloor moves apart and magma rises?
Seafloor Spreading
What happens at a hydrothermal vent?
At a hydrothermal vent, seawater is heated by magma beneath the seafloor, creating hot, mineral-rich fluids that are released into the ocean. These fluids support unique ecosystems by providing energy and nutrients for organisms like tube worms, giant clams, and bacteria. Hydrothermal vents also play a role in the ocean's chemistry and can deposit minerals on the seafloor.
How did harry hess hypothesis explain seafloor movement?
Harry hess' hypothesis was hot/less dense material rises up the Earth's crust toward the mid-ocean ridges. When the seafloor breaks apart, magma is forced upward and through the cracks. It cools, and becomes a new seafloor. When it moves away from the mid-ocean ridge, it becomes denser and sinks. This helps form ridges.
How does magma rise to the surface of the Earth?
Through cracks, holes or vents in the earths crust.
What is the effect of magma pushing up through cracks in the ocean floor?
push and a pull
