What do hot spots and mid ocean ridges have in common?
rising magma moves due to density differences
How can ridges be created by tectonics?
The mid-ocean ridge is a volcanic feature caused by the spreading apart of oceanic plates as part of plate tectonics, and is initially formed as a result of changes in the convection currents which seek the least resistant point to the surface. The sea floor at the ridges are uplifted by rising magma. The rising magma is part of a process of heat transfer from the interior of the Earth to the surface known as a convection current. As the rising magma cools, it forms new crust which becomes part of the ridge.
How does oceanic crust form at constructive plate margins?
Do you mean spreading centres or oceanic ridges, where the oceanic lithosphere is renewed by hot, less dense rock rising in convection zones.
What are the mountains in the ocean called?
Volcanic Islands. It was a term used by explorers who didn't know the earth was round. They though it was flat and didn't understand why the mountains looked as though they were rising out of the sea. Because the earth is round landforms and mountains for example look as though they are rising out of the ocean.
If you can see the moon in the east it is an what moon?
That all depends what time of day you see it in the east. If it's rising in the east within a few hours before the sun, it's a waning crescent. If it's rising in the east around Noon, it's at First Quarter, and appears half illuminated. If it's rising in the east just as the sun is setting in the west, then it's full. If it's rising in the east around midnight, then it's at Last Quarter, and is half illuminated.

What page is the word incense on in Esperanza Rising?
The word "incense" appears on page 117 of the book "Esperanza Rising" by Pam Muñoz Ryan.
Name types of plate boundarys found when two plates separate?
These are called divergent plate boundaries marked by ridges, caused by the uplift of crust by rising magma, on either side of a rift valley, where the magma fills in the gap left by the spreading ridges.
How can ridges be created by tectonics?
The mid-ocean ridge is a volcanic feature caused by the spreading apart of oceanic plates as part of plate tectonics, and is initially formed as a result of changes in the convection currents which seek the least resistant point to the surface.

As the rising magma cools, it forms new crust which becomes part of the ridge.
Why is so much basaltic magma erupted along mid-ocean ridges?
Lowered pressures decrease the temperatures at which basalt magma can partially melt from a rising plume of mantle peridotite.

What is the theory that explains how new crust is formed along a great crack in Earth's ocean floors?
The creation of oceanic crust at the mid-ocean ridges is part of the all encompassing theory of plate tectonics. The mid-ocean ridge is a volcanic feature caused by the spreading apart of oceanic plates as part of plate tectonics. The sea floor at the ridges are uplifted by rising magma. The rising magma is part of a process of heat transfer from the interior of the Earth to the surface known as a convection current. As the rising magma cools, it forms new crust which becomes part of the ridge.

What the mid-ocean ridges?
The mid-ocean ridge is the Earth's longest continuous mountain range, approximately 55-65 thousand kilometers long and bilaterally divided by a valley called a rift. The mid-ocean ridge is a volcanic feature caused by the spreading apart of oceanic plates as part of plate tectonics. The sea floor at the ridges are uplifted by rising magma. The rising magma is part of a process of heat transfer from the interior of the Earth to the surface known as a convection current. As the rising magma cools, it forms new crust which becomes part of the ridge. Therefore, the ridge is composed of basalt and gabbro, and is among the most recent of geologic age crustal rock. :)
What causes the formation of mid-ocean ridges?
they are formed from the uplift of newly formed oceanic crust by rising magma.
How do igneous rocks form after rising to the surface?
they form in three main places where lithospic plate pull apartat mid-ocean ridges,where plates come together and making it thicker amd allowing to melt,see more at About Volcanism.
Who appears the most in the 'Hannibal' movies?
There are five so-called "Hannibal" movies. Frankie Faison appears in four of them: Manhunter, Silence of the Lambs, Hannibal and Red Dragon. He is Lt. Fisk in Manhunter and Barney Mathews in the remainder. None of the actors in the first four movies appears in the fifth movie, Hannibal Rising.
