When data from the Earth's magnetic field locked inside seafloor rocks became widely understood, most skeptics around the world were convinced that seafloor spreading occurs and that the concept of plate tectonics is valid. True / False.

True

Explanation:

TRUE

Explanation:

The basaltic rocks that are erupted at the seafloor are comprised of magnetic property, where the iron minerals are oriented in the north/south direction. It has been observed that the earth's magnetic polarity alters every time it erupts. This played a key role in determining that the seafloor spreading is taking place and which further provided as key evidence for the proving of the plate tectonic activity. The rocks formed at the mid-oceanic ridge are the youngest, and moving away from it, the age of the rocks increases.

Thus, the above-given statement is True.

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
