The scientists that are concerned about increased carbon dioxide in the atmosphere believe global warming is caused by human actions.
Explanation:
The global warming is a fact, but there is a big debate about the main causes of it. On one side are the scientists that believe that the human actions are the main cause of the global warming, on the other side are the scientists that believe it is strictly a natural process, and in the middle are the scientists that believe it is caused by both the human actions and the natural processes.
The scientists that believe that the global warming is caused by the human actions often discount the natural processes and their importance. The human actions increase the effect of the natural processes, but lot of scientists tend to exaggerate the human effect. If the trend of carbon dioxide input into the atmosphere by the human activity at this rate, then in the future it will most probably became a very important factor, while for now is relatively low when compared to the natural processes.
The majority of the carbon dioxide from the human activities comes from:
- burning of coal
- combustion of oil
- burning of wood
This is mainly done through:
- industry
- transportation
- agriculture
- heating of homes

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

Answer:
Explanation:
There are two dominant theories:
The inside-out model proposes that the Earth formed with trace amounts of water structurally bonded to the minerals in the mantle. This water makes its way to the Earth’s surface through volcanic processes.
The outside-in model proposes that the Earth formed without water, which came with other volatiles from the meteorites or comets that bombarded the young planet. This water was probably mixed into the upper layers of the Earth and was later brought to the surface through volcanism.
