Which layer creates the earth's magnetic field inner or outer and which layer is the source of the Earth's rocks?
The outer core creates the Earth's magnetic field, and the mantle is the source of the Earth's rocks.
The outer core is a liquid layer of iron and nickel that surrounds the solid inner core. The motion of the liquid in the outer core generates electric currents, which in turn generate the Earth's magnetic field.
The mantle is a solid layer of rock that lies between the outer core and the crust. The mantle is much thicker than the crust, and it makes up about 84% of the Earth's volume. The mantle is very hot, and the rocks in the mantle flow slowly over time. This flow of rock is what drives plate tectonics, which is the process that creates and destroys mountains, continents, and oceans.
The rocks of the crust are derived from the rocks of the mantle. When volcanoes erupt, they release molten rock from the mantle. This molten rock cools and solidifies to form new crustal rocks.
The generation of Earth's magnetic field occurs deep within the Earth's interior, in a layer known as the outer core to be precise. Here the convective energy from the slow-moving molten iron is converted to electrical and magnetic energy,The swirling motion of the outer core generates Earth's magnetic field in a process called geodynamo, according to NASA Earth Sciences. Magnetism inside Earth's core is approximately 50 times stronger than it is on the surface.The Earth's magnetic field is created by the Earth's metal core. Movement within the core between the solid and liquid parts of the core creates convection currents. There are several metals within the core, but iron creates electrical currents as it moves, thus generating the magnetic field. The Earth has a solid inner core and a liquid outer core, both made of iron and nickel. The metal carries an electrical current that is powered by the movement of the liquid. The electrical current creates a magnetic field that reaches out from the core to the surface of the Earth and beyond. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core. Earth's crust is composed of two types of crust: continental crust and oceanic crust. Continental crust is less dense, older, and made up of granite and quartz that are high in silicon and oxygen. Oceanic crust is denser, younger, and made up of mostly basaltic rocks like gabbro.The crust of the Earth is called as lithosphere. This layer is composed of the mantle and the crust. Most part of the Earth's crust is covered by the oceans.
The convective current in the outer core of the earth is responsible for magnetic field of the earth.

The outer core creates the Earth's magnetic field, and the mantle is the source of the Earth's rocks. The outer core is a liquid layer of iron and nickel that surrounds the solid inner core. The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface. The mantle is the thickest layer of the Earth, making up about 82% of its volume. The mantle is composed primarily of heavy metals, such as iron, nickel, magnesium, and others. Scientists describe the state of the mantle as 'plastic. The outer core is responsible for Earth's magnetic field. As Earth spins on its axis, the iron inside the liquid outer core moves around. The movement causes powerful electric currents to develop in the liquid iron itself.The generation of Earth's magnetic field occurs deep within the Earth's interior, in a layer known as the outer core to be precise.
