How do magnetic stripes of iron in ocean rock provide evidence of seafloor spreading? they show when earth's poles reversed. they show how the density of the seafloor has changed. they reveal a matching pattern on either side of the ridge. they reveal differences in the mineral composition of newly created rock.

They reveal a matching pattern on either side of the ridge

They reveal a matching pattern on either side of the ridge

Explanation;

Sea-floor spreading occurs when the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them. Several types of evidence supported Hess's theory of sea-floor spreading, these includes; eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. Magnetic stripes in the rock of ocean floor reveal a matching pattern on either side of the ridge and this provides evidence of sea floor spreading

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
