Answer:
The geosphere hosts elements like oxygen, iron, hydrogen, silicon, calcium, magnesium, aluminium, etc.
Step-by-step explanation:
- Elements that are majorly found in the geosphere (the "solid part of the Earth" consisting of the crust, mantle and the core) are oxygen, iron, silicon and magnesium, hydrogen, etc.
- Thousands of other substances found on Earth are made up of these basic elements.
- These elements constitute about 98% mass of the entire Earth. Oxygen is the most abundant element found in the geosphere.
