Describe the two types of crust
WebThe mantle is the layer beneath the crust and is made up of dense, semi-solid rock. The outer core is a liquid layer of iron and nickel surrounding the solid inner core, which is also made of iron and nickel. The lithosphere is the rigid, outermost layer of the Earth that includes the crust and uppermost part of the mantle.

WebMar 8, 2024 · The ball-shaped core lies beneath the cool, brittle crust and the mostly solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles). Planet Earth is older than the core. When Earth was formed about 4.5 billion years ago, it was a uniform ball of hot rock. WebAt the center of the Earth is a hot, dense metal core. The crust and upper mantle are part of a single geological unit called the lithosphere. The Earth's crust is made up of igneous, metamorphic, and sedimentary rocks. Most common rocks are igneous rocks that form when magma cools. Crust is divided into two types: oceanic crust and continental ...
WebThe Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time. A divergent boundary occurs when two tectonic plates move away from … WebContinental crust is mostly granite, a coarse-grained igneous rock, and oceanic crust is mostly basalt, a fine-grained igneous rock. Granite is rich in minerals containing silica and aluminum and basalt is rich in minerals containing iron and magnesium. Continental crust is thicker and less dense than oceanic crust.
