<span>It is true that ozone is both helpful and harmful to life on Earth. On one hand, there is the ozone layer in the atmosphere that protects the Earth from direct sun rays, and thus it protects us and the life on our planet from burning up. However, on the other hand, considering that it can be found in the air, it can be harmful to organisms that breathe it in, as it can cause problems with lungs. Also, it is a pollutant, and it is gradually destroying nature and crops on our planet. </span>
Answer:
a) divergent boundaries by submarine eruptions and intrusions of basaltic magma
Explanation:
Divergent boundary is where tectonic plate move apart from each other. Divergent boundary is mostly prevalent in the oceanic crust. The opposing plate tends to move apart from each other.
On the oceanic crust plates move apart from each other causing an upwelling of magma from the aesthenosphere. This magmatic material is introduced through the oceanic ridges. As the magma are introduce the opposing plates separates further . The basaltic magma introduced through the oceanic ridges forms the new oceanic crust. As we move away from the oceanic ridge the rocks gets older . The oceanic ridge where the basaltic magma erupt depict the youngest rocks.
Answer:
They travel through solids.
Explanation:
P waves are faster than S waves and are capable of travelling through any medium. S waves are also known as secondary waves. They move more slowly than P waves and also move perpendicularly to the direction of movement. S waves can travel through solids like P waves, but they cannot move through liquids. The fact that S waves are not present in the outer core of the Earth is a hint that this layer is probably liquid.
