Natural cracks in the rock that form due to the exhumation of deeply buried rock are called salt wedges.
Answer: Option 1
<u>Explanation:
</u>
The process of exhumation in the discipline of Geography refers to digging up of a buried rock due to natural forces applied on the surface under which the rock is buried. At a salt wedge, a river flowing with a great velocity meets the ocean where the ocean is comparatively calm.
The fast-flowing river water acts as a digging force and carries out the process of exhumation of the rocks at the wedge. The same fast-flowing water creates cracks in the exhumed rocks.
Answer:
D. Seafloor bedrock is younger near the ridge and older farther away.
Explanation:
In a divergence boundary oceanic plates or continental plates move apart. The plates moves apart causing an uprising of molten magma to form a new crust. The divergent movement of plate is very prevalent in the oceanic plates.
The plates in the oceanic crust moves apart due to the up welling of aesthenosphere materials . These aesthenosphere materials(molten magma) are introduce to the ocean floor through the mid oceanic ridge . As this materials are introduced through cracks and fissures, the plates continue to drift apart. The molten magma later solidified to form a new crust closer to the oceanic ridge. This is why sea floor bedrock closer to the ridge is younger as new rocks are formed here. But as one move farther away from the ridge the rocks become older. This phenomenon provide ample evidence that the seafloor is spreading. The older rocks found father away from the ridge proves the seafloor has been spreading given way for new rocks closer to the ridge.
C) Increased access to an area
