What are the elements of the hydrosphere
Answers
Answer:
Different elements are found in the lithosphere, biosphere, hydrosphere, and atmosphere.Scientists divide Earth into many different sections, or spheres. Each sphere containsonly a small number of different elements. However, these elements are found in different amounts in different spheres. Let’s take a closer look at the elements that are found in four of the most important spheres.
• Lithosphere: The lithosphere is the solid part of Earth, including the crust. It contains rocks and minerals. Oxygen and silicon are the most abundant elements in this sphere. There are also small amounts of metals such as aluminum, iron, calcium, and sodium.
• Biosphere: The biosphere contains Earth’s living matter. All plants and animals are part of this sphere. Oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus are the most abundant elements in living things.
• Hydrosphere: All of the water on Earth is part of the hydrosphere. The main component of the hydrosphere, the oceans, makes up more than 70% of Earth’s surface. Because water is made of oxygen and hydrogen atoms, these two elements are the most common in the hydrosphere. Because ocean water contains salt, there is also sodium and chlorine in the oceans.
• Atmosphere: The atmosphere includes the air that surrounds Earth. Remember that air is a mixture of different gases. The most abundant of these gases are nitrogen, oxygen, and argon.
Based on the information you just read, complete the following Venn Diagram. If an element is found in all 3, the element name goes in the middle of the Venn Diagram. If an element is found in 2 of the 3, the element name goes in the circle between them. First, write the chemical symbols for the elements in the word bank. Use only the chemical symbols to fill in the Venn Diagram.
