Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
the answer is agriculture
Answer:
(-8, 6)
Explanation:
Where ever the school is starting off on the grid you should take away 8 and add 6 to Janet's new location. This is so that your answer is correct.
Janet is 8 blocks west and 6 blocks north of where she began.
Answer:
Rocks, water, and air—indeed, most materials—expand and thus become less ... that led to the formation of Earth's core) contributes 20 to 50% of the heat. ... Mantle convection is the main way heat from Earth's interior is transported to ... tectonic plate movement would also stop including earthquakes and volcanic activity.
Explanation:
Answer:
In a divergent plate boundary, two plates move away from one another. Due to this divergent movement of plates, seafloor spreading takes place in the ocean basin along the mid-oceanic ridge and rifting take place in the continental areas. Due to the stretching of the crust, the lithosphere becomes thin, and with more progressive spreading, it results in the eruption of magma at the seafloor. This magma is basaltic in nature, that reaches the surface due to the force exerted by the uprising magma forming convection cells in the mantle. This type of plate motion results in the expansion of the ocean basin and the rift valley in the continental areas forms seas and oceans with increasing time.
The rocks that are formed at the mid-oceanic ridge are the youngest as the magma cools and solidifies very rapidly here. With further moving away from this spreading center the age of the rocks increases.
The divergent plate boundaries are also responsible for the occurrence of deep-focus earthquakes, and it also leads to the formation of volcanoes in its adjacent sides.
