<span>A climate cycle in the Pacific Ocean with a global impact on weather patterns is called El Nino. The cycle begins when warm water in the western tropical Pacific Ocean and shifts eastward along the equator toward the coast of South America.
La Nina has cooler temperatures, not warmer ones. Temperature inversion is just a simple change of temperature. And global warming doesn't fit here as it is not a type of current.</span>

B. Both continental and ocean-floor topography are measured relative to sea level
Explanation:
On a topographic map, both continental and ocean-floor topography are measured relative to sea level.
The sea level is the reference surface for the continental and ocean floor topography.
- A topographic map is a map that shows landform using series of contour lines.
- The lines joins places of equal elevation.
- The elevation is usually referenced to the sea level surface.
- The sea level is taken as the surface with 0 depth or height.
- Continental topography is all places above the sea level.
- Ocean floor is below the sea level surface

We cannot live without water. Saving water helps to preserve our environment. It reduces the energy required to process and deliver water, which helps in reducing pollution and in conserving fuel resources. Saving water now means having water available in the future for recreational purposes, too.
<span>Fresh, clean water is a limited resource. While most of the planet is covered in water, it is salt water that can only be consumed by humans and other species after undergoing desalination, which is an expensive process.
