A. The rate of photosynthesis must be greater than the rate of respiration
sea level can rise in response to thermal expansion, atmospheric pressure changes, changes in sea ice extent.
<h3>What happens if sea levels rise?</h3>
The main physical effects of sea level rise are beach erosion, inundation of deltas, flooding, and the loss of numerous marshes and wetlands. As a result of saltwater intrusion, increased salinity will probably become a concern in coastal aquifers and estuary systems.
<h3>How is sea level rise measured?</h3>
Tide stations and satellite laser altimeters are the main tools used to measure sea level. The height of the sea as measured along the shore in relation to a particular place on land is what tide stations all around the world tell us about what is happening locally.
<h3>How will sea level rise affect us in the future?</h3>
And as the oceans get larger due to a rising climate, more people may be at risk of coastal flooding by 2100, putting up to 410 million people at risk. The increase of coastal towns as a result of building and development also puts more people at risk.

Hey there,
They both have grassy and green lands and they are basically used for farming and crops and things like that.

Answer:
geomagnetic field.
Explanation:
The earth magnetic field can be likened to a bar magnet with a North and South pole. It originates from the movement of molten iron and nickel in the outer core.
At every point in time, the magnetic field orientation can change. We must note that the magnetic north lies close to that of geographic north axis of the earth.
Around the mid-oceanic ridges, new materials are brought to the surface. These new materials can contain magnetic minerals such as haematite which are capable of being magnetized as a result of the prevalent magnetic field of the earth. As different materials are brought up, the magnetic minerals preserves the details of the magnetic field at that point in time. Using this information can know the orientation of the magnetic field at any point in time if the magnetic history chart of the earth is constructed. Oceanic ridges becomes older as they move away from the divergent margins.
