Answer: C.)according to Earth’s existing magnetic field

Explanation:

Earth acts as a huge bar magnet.  It has strong magnetic field due to presence of molten iron and nickle present in its outer core. A magnetic object acquires magnetic properties when placed in a magnetic field for a while.  

Basalt is a volcanic rock. It is formed due to rapid cooling of lava on the surface of Earth. It contains iron oxides, iron-titanium oxides. Because of these oxides, Basalt can acquire strong magnetic properties. The domains align in the same direction as the Earth's magnetic field.

Thus, when new basalt forms along mid-ocean ridges, it becomes magnetized <u>C.) according to Earth’s existing magnetic field </u>

Maslowich

Answer:

For a change in the environment that surrounds them.

Explanation:

Frogs and toads are amphibians that have the ability to live in both environments, that is why their respiratory system is highly adapted to extreme situations such as sudden climate changes, among others.

This modification of the environment many species would not tolerate because generally species always develop, live and reproduce in a single environment, such as humans, which is only in the terrestrial environment.

It is very difficult for frogs not to be able to adapt or survive climate change since they have the ability to adapt their respiratory system to two totally different media such as water and air.

kondaur [170]

Answer:

D. atmospheric aerosols.

Explanation:

<em>Atmospheric aerosols are tiny particles that float in the air. These particles could be liquid or solid and are usually suspended primarily by direct emission into the atmosphere or secondarily by condensation process. </em>

Atmospheric aerosols have numerous effects on the biotic and abiotic factors of the environment. They alter air quality and impact human health in some cases, they can reduce atmospheric visibility, and they also reduce the amount of radiation that reaches the earth by scattering or reflecting some of the radiations from the sun back into space, leading to cooling of the atmosphere.

A substance with a ph of 5 is called
ddd [48]

Answer:

A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.

Please said thanks
