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.

  • Jupiter also consists of upper clouds, located in the low-pressure range are made of ammonia ice. Auroras are a permanent feature of the Jupiter's atmosphere based on the exiting models temperature predictions of the atmosphere are no higher than 400k.
  • Strong jets have been observed at the equator of the by the deep models. Temperature and winds are found to rise from the equator to the poles, thus confined within zones. As a comparison to the anticyclones, the jovian cyclones tend to be small dark and irregular.
