Water pollution affects marine ecosystems by completely killing it off. Pollution kills fish, reefs, and other underwater life. With this pollution, animal's behaviors can change, and habitats are destroyed.
I hope this helped, and I hope you pass your assessment!
Answer:
Rocks found on different mountains are different ages.
Explanation:
Radiometric dating of rocks and fossil records gives scientists an idea of the timelines of certain organisms. Fossils of long dead species found in different strata of rocks can be used to speculate the age and changes these organisms have experienced overtime.
Fossils found in the uppermost strata are indicative of organisms that died not quite long whereas fossils found in lower layers are indicate of organisms that died a long while ago. These studies also provide insight into the changes that the earth has experienced overtime.
Answer:
The active volcanoes are gradually moving away from the oceanic ridge.
Explanation:
- Many oceanic volcanoes occur as long lines of the active end of volcanoes as here in the mid-oceanic ridges the plate is pushed far away from the ridge surface of the earth as these tend to move out in the direction of the movement of the plates.
- Thus the volcanoes are generally found near the active zones or regions of the tectonic plate and associated with the earthquakes occurring on the fault line or shear lines of the plates.
- Spreading of the ridges as a result of the seafloor spreading takes place and the mantel and plates from below are the driving forces that make the volcanoes and convection current that rises through the mantle pushes or spread the volcanoes to the sides like seen in the ring of fire.
Very acuratley, once the rate of birth, mortality rate, and infant mortality rate are taken into perspective.
More, more. Because the ocean is more deep and thick and its more colder than shallow warm water
