Answer:
because volcanoes in the center of the ridge push the pre-existing seafloor on either side of it away from it at equal speeds
also when the earth's polarity flips, the crystals on either side of the spreading center are affected equally, so the bands are always the same distance from the ocean ridge
also because when the magma solidifies (which is what "freezes in" the magnetic orientation), the magnetic field of the earth exerts the same force on both sides of the ridge (the midline of the spreading).
Explanation:
Answer:
Oil and coal are two of the most used fossil fuels by modern societies for the creation of goods and services, as well as for the mobilization of people through vehicles. Therefore, they constitute the most important raw materials for human subsistence, along with water and food.
For this reason, social awareness and the culture of caring for the environment directly affects the use of these goods, since an overexploitation and eventual extinction of these natural products would imply a series of extremely negative consequences for the human species in general. In addition, the necessary care in its use must be strictly contemplated, in order to avoid contamination situations that affect the quality of life in general.

Animals
Explanation:
Sponges are the simplest and most primitive animals on earth. They are found in continental water bodies, where 98% of the population are found in salt-water and the remainder in fresh-water.
They have little or no defined organs and movement is hardly noticed in adult sponges, feed by filtration, and have a rather flexible skeletal structure.
Answer:
vertical and horizontal symmetry
