Solution

Ice rafted debris is identified in marine sediment cores as sand and gravel.

Here's the step by step explanation:

  1. Ice rafted debris refers to the sediment of various sizes transported by icebergs. As these icebergs melt, they drop this sediment into the sea, which then becomes part of the marine sediment.

  2. This debris can range in size from tiny particles to large rocks. However, in marine sediment cores, the most commonly identified ice rafted debris is sand and gravel.

  3. Red clay, manganese nodules, graded beds, shells and ooze are also types of marine sediments, but they are not typically associated with ice rafted debris.

  4. Therefore, the correct answer is sand and gravel.

Marine DebrisSource: National Oceanic and Atmospheric AdministrationMarine debris is a persistent pollution problem that reaches throughout the entire ocean and Great Lakes. Our ocean and waterways are polluted with a wide variety of marine debris, ranging from tiny microplastics, smaller than 5 mm, to derelict fishing gear and abandoned vessels. Worldwide, hundreds of marine species have been negatively impacted by marine debris, which can harm or kill an animal when it is ingested or they become entangled, and can threaten the habitats they depend on. Marine debris can also interfere with navigation safety and potentially pose a threat to human health.All marine debris comes from people with a majority of it originating on land and entering the ocean and Great Lakes through littering, poor waste management practices, storm water discharge, and extreme natural events such as tsunamis and hurricanes. Some debris, such as derelict fishing gear, can also come from ocean-based sources. This lost or abandoned gear is a major problem because it can continue to capture and kill wildlife, damage sensitive habitats, and even compete with and damage active fishing gear.   3Select the correct answer.What is the key idea of this passage? A. Littering is harmful to the water supply and marine life. B. Marine pollution is not only devasting to marine life, but to human health. C. Hunting and water sports are endangering the safety of marine life. D. People are the main cause of marine pollution.
