• The core consists of two parts - an inner solid core and an outer liquid core.
• The mantle is the thickest layer, composed mainly of magma (molten rock) and solid rock.
• The movement of tectonic plates is driven by the heat generated by radioactive decay in the Earth's interior.
• Plate boundaries are where the plates interact, leading to phenomena like earthquakes, volcanic activity, and mountain-building.
• The theory of plate tectonics states that the Earth's outer shell is divided into several plates that glide over the mantle.
• The Earth's crust is the outermost layer, made up of solid rock.
• The Earth's crust is the outermost layer, made up of solid rock.

• The core consists of two parts - an inner solid core and an outer liquid core.
• The mantle is the thickest layer, making up about 84% of Earth's volume.

• The crust is the thinnest layer but is where most human activity takes place.
• The crust is the thinnest layer but is where most human activity takes place.
• Earthquakes are caused by sudden movements along fault lines or fractures within the lithosphere.

• The crust is the thinnest layer, made up of rocks that are cooler than those found deeper inside the Earth.

• The mantle lies between the crust and the core, consisting mostly of magma (molten rock).
• The mantle lies between the crust and the core, consisting mostly of magma (molten rock).
• The Earth's core consists of two parts - an inner core and an outer core.
• Sea floor spreading occurs at divergent plate boundaries, with new crust forming as molten rock from the mantle fills gaps between separating plates.
• There are three types of plate boundaries: divergent, convergent, and transform.
• Divergent plate boundary occurs when two plates move away from each other.
• There are seven major continental plates and several smaller ones.
• Convection currents within the mantle drive the motion of these plates.
• There are seven major continental plates and several smaller ones.
• Convection currents occur when hotter material rises while cooler material sinks, creating convective cells that drive plate motion.
• Plate tectonics refers to the movement of large plates on the surface of the Earth's lithosphere.
• Convection currents occur when hotter material rises while cooler material sinks, creating convective cells that drive plate motion.
• Convergent plate boundary occurs when two plates move towards each other.
• The atmosphere is composed mainly of nitrogen (78%) and oxygen (21%).
• Core - The core is the innermost part of the Earth, consisting of a liquid outer core and a solid inner core.
