When new basalt forms along ocean ridges it becomes magnetized how?
While it is molten it is above the Curie temperature and is not magnetic, as it cools below this temperature the ambient magnetic field becomes "frozen" into the basalt.
What happens under the earth when a earthquake forms?
shakes
Which forms of settlement develops along either side of roadsrivers or canals?
linear
What is a deep valley on land that forms along a spreading boundary?
rift valley
Which type of moraine forms along each side of a glacier?
A medial moraine.
When new basalt forms along mid oceans ridges it becomes magnetized?
accorsing to the earths magnetic field

When new basalt forms along mid-ocean ridges it become magnetized?
accorsing to the earths magnetic field
What is the color and the type of rock that forms oceanic crust at mid ocean ridges?
The color of rocks that forms the oceanic crust at the Mid Ocean Ridge are dark (blackish) color and they are dense and ferromagnetic in property. The major rock type is Basalt.
What happens when new basalt forms along mid ocean ridges it?
The molten material then spreads out, pushing the older rock to both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. Then more molten material flows into the crack. The material splits apart the strip of solid rock that formed before, pushing it aside.
What kind of rock is igneous rock that forms on earth's surface?
Basalt is extruded from volcanoes and MOR (mid ocean ridges). It actually forms in the earth's mantle and just solidifies on the earth's surface.
What are some facts about basalt?
Basalt is a dark-colored igneous rock that forms when low-silica lava cools on Earth's surface. It may commonly have vesicles. It often forms two types of lava flow: pahoehoe with smooth surfaces and a'a with rough surfaces. Basalt is commonly formed at mid-ocean ridges, oceanic hot spots, and in continental flood basalts.
Does basalt form on the oceanic crust?
Basalt is an extrusive, volcanic rock. It commonly forms the volcanic mountains found in the Oceans - eg Hawaii is made of basalts.
Some of the newest crust in the world forms along the mid-ocean ridges True or False?
true
What type of magma forms at mid-ocean ridges?
pillow lava named that because when it cools it looks like pillows.
Which forms at mid-ocean ridges?
New oceanic crust is created along mid ocean ridges. These are areas of the earth where there is divergence or splitting of the ocean floor and basaltic magma oozes out from within the mantle to occupy the gaps and form new crusts.
Low silica magma forms rocks like?
it forms Basalt.
