Tips for using the tracing numbers worksheets. Start with the writing numbers worksheet for number 1. That is not only the first number your child will begin counting with, but it is also the easiest number for children to write. Direct your child to trace each number following the direction of the arrows to learn the proper formation.
Marine debris can enter the ocean in a variety of ways. From land, trash may be carried to the ocean in rivers or storm and sewage drains, swept from the beach by waves and surf, or blown offshore by winds, especially during heavy storms.he most common way to measure floating plastic in the ocean is to collect it using very fine-meshed nets towed at the ocean surface from a ship. At SEA we have been measuring plastic debris using this method for more than 25 years.
Beach Sediments can range from silt, sand, gravel to boulders. Most sand has its origins from rocks on the land. The sand at Muriwai is mainly black iron sand (also known as Titomagnetite). This sand originates from the volcanoes of the Central North Island and Mount Taranaki on the West Coast. Rivers from these mountainous regions have eroded volcanic material and carried sediment to the sea. From there longshore drift has transported the black sand up the coast and deposited on beaches.
