Answer:
Terrigenous
Explanation:
The sediments must have been land derieved.
Garnet and zircon are found associated with igneous and metamorphic rocks.
Weathering of these rocks release the minerals into sediments and are hereby transported into ocean basins. They can lithify in the sediments as they get carried along with them.
Terrigenous sediments originates from the land. They are made of rock materials and volcanic deposits. Some of them like volcanic dusts can travel into deeper parts of the oceans as they are lighter and can be carried very far into the ocean.
After looking at the map/picture you have given above. There are several reasons why location D has a cooler climate than location E. Some of the reasons are a higher altitude, father north of the equator, location E is closer to the equator.
Because they have the most to lose, imagine it like you have 10 towers and all collapsed from a tsunami. And the village next to you also collapses. The ten towers lost way more money and people in it then the villages
In short answer, The developed country just simply has a lot more to lose then the lesser developed one.
