Which of these describes a method in studying plate movements?

-observing the absence of magnetic rocks in locations that do not match the poles
-match relief elements only on the western side of the atlantic ocean
-recording the spread of the seafloor in the mid-atlantic region
-correlate the rotation of earth to plate movement

Answer:

C: Recording the spread of the seafloor in the mid-Atlantic region .

This describes a method in studying plate movements

Explanation:

Seafloor spreading is the ‘process’ by which oceanic crusts are formed as a result of volcanoes. Then these crusts slowly drift away from the edge/ridge. It usually occurs at mid-ocean edges.

When plates move, they collide. Because of these collisions volcanoes and earthquakes occur. Volcanoes occur when one plate sinks under another plate. This allows the lava to get inside the plates and volcano occurs after the build-up of this magma or lava. Earthquakes are caused when two plates collide and slide with each other. Thus, Option C is the correct answer as plate movements eventually cause se floor spreading.

explanation:

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
