Answer:
Options (3), (4) and (5)
Explanation:
The geographic north and south poles refers to the two geographical location/points, where the earth's axis spins. And the magnetic north and south poles refers to the direction towards which a compass needle points.
The geographic north pole and the magnetic south pole of earth is the same, and two bar magnets where one having the north pole and the other having the south pole can attract each other. Similar poles of two bar magnets cannot attract one another, whereas they repel.
Thus, the correct answers are options (3), (4) and (5).
It slowly makes the ground softer making it easier for it to dissolve

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.
