Identify and describe the different layers of the Earth based on the provided diagram and questions.

Welcome back — been a while! Let's pick up where you left off. The diagram shows the layers of the Earth: 1: Crust 2: Mantle 3: Outer Core 4: Inner Core 1.1: Give two names of layer of 2. Layer 2 is the Mantle. It is commonly divided into: • Upper Mantle • Lower Mantle 1.2: Give two names of layers of 3. Layer 3 is the Outer Core. It is primarily composed of: • Liquid Iron • Nickel 1.3: Name two layers of the earth that consist of Sial and Sima. Sial (silica and aluminum) is found in the continental crust, and Sima (silica and magnesium) is found in the oceanic crust and upper mantle. • Crust • Upper Mantle 1.4: Identify two layers of the earth that are in a semi-molten state. • The Asthenosphere (part of the upper mantle) is semi-molten. • The Outer Core is liquid, which is a fluid state. 1.5: Which layer experiences the hottest temperature and highest pressure? Temperature and pressure increase with depth. The deepest layer is the Inner Core. • Inner Core Send me the next one 📸
