The correct answer would be rift. If you looked at the crossword puzzle it showed you the answer.
The East African Rift is the greatest continental crack on Earth's surface. It is a tectonic plate boundary where the African Plate is splitting into two new plates, causing the land to slowly separate over millions of years. This rift is an active geological feature and is expected to eventually form a new ocean basin as the plates continue to drift apart.
When Earth's plates spread apart, it is known as seafloor spreading. This process occurs at mid-ocean ridges where new crust is formed as magma rises up from the mantle and solidifies. As the plates move apart, they create new oceanic crust.
A vent is an opening in the Earth's surface where gas or magma can escape, while a rift is a crack or fissure in the Earth's crust where tectonic plates are pulling apart. Vents are typically associated with volcanic activity, while rifts are formed by the movement of tectonic plates.
plate tectonics, which is the movement of the Earth's lithosphere. This movement occurs due to the convection currents in the Earth's mantle, causing plates to gradually shift and separate from each other. The process of seafloor spreading at mid-ocean ridges is a common example of plates moving apart.
When Earth's plates spread apart, it creates a divergent boundary where new oceanic crust is formed as magma rises from the mantle and solidifies. This process leads to the creation of features like mid-ocean ridges and rift valleys.
Those are earthquakes
Because the earth plates were weak it that area and the small eruption and it began a crack and water from the ocean/sea came into the crack causing the rack to increase between 4-18 miles apart
the plates are apart of the crust,the upper layer of the earth
The huge crack in the Earth's surface that starts in Iceland is known as the Mid-Atlantic Ridge. It is a divergent boundary between the Eurasian and North American tectonic plates, where new oceanic crust is formed as the plates pull apart. This geological feature is significant for its role in plate tectonics and underwater volcanic activity.
Magma that has bubbled up through the crack in the Earth's surface.
Faults, graben and mid oceanic ridges.
magma
Divergent boundaries such as the Mid-Atlantic Ridge and East Pacific Rise are examples of earth plates spreading apart slowly. This process results in the continuous formation of new oceanic crust as magma rises to the surface and solidifies.
divergent boundary
separation zone.
A crack or opening in the Earth's crust is known as a fault. Faults are caused by tectonic forces that create stress and movement along the plates, resulting in fractures in the Earth's crust. Movement along faults can cause earthquakes.
