How to draw a stick figure of the sea

Sea Sketch Course: Sea Sketch Course 1. The sea introduces the terms of ocean and earth science, and is the general name of the widest water body on the earth. The earth's surface is divided into huge interconnected water bodies by the mainland, which are called oceans. The central part of the ocean is called ocean, and the marginal part is called sea. They communicate with each other and form a unified water body. ?

The total ocean area on the earth is about 360 million square kilometers, accounting for 7 1% of the earth's surface area, with an average water depth of about 3795 meters. The ocean contains more than1350 million cubic kilometers of water, accounting for about 97% of the total water of the earth, and only 2% is available for human consumption.

The four oceans of the earth are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean and the Arctic Ocean, and most of them are bounded by land and seabed topographic lines. Today, only 5% of the seabed has been explored, and 95% of the seabed is unknown. ?

The ocean covers more than 70% of the earth's surface and is the main driving force of weather and climate. Slight fluctuations in ocean temperature may lead to drastic changes in global weather and climate. ?

Because the ocean area of the earth (about 360 million square kilometers) is much larger than the land area, some people call the earth a "big water polo". The Pacific Ocean, the Atlantic Ocean and the Indian Ocean account for 46%, 24% and 20% of the total ocean area of the earth respectively.

Most of the important marginal seas are distributed in the northern hemisphere, and some are surrounded by continents or islands. The largest are the Arctic Ocean and its offshore waters, the Mediterranean Sea, the Caribbean Sea and the waters around the European Red Sea, the Bering Sea, the Sea of Okhotsk, the Yellow Sea, the East China Sea and the Sea of Japan.
