Science

In science we are learning about the earth's crust. We learned about the core/crust of the earth, the lithosphere, igneous rock, sedimentary rock , metamorphic rock, mantle, and asthenosphere.

The core of the earth is the inside layer of the earth. The earth's inner core is extremely burning hot and not possible to travel to because of temperature and rigid. The earth's outer core is still impossible to travel to because of temperature but is not rigid it's more of a liquid. The crust of the earth is a thin layer of skin of the earth. The crust is the outermost solid shell of a rocky planet or natural satellite.

The lithosphere is the crust and upper-most solid mantle or the rigid outermost shell of the earth. Igneous rock is formed through the cooling and solidification of magma or lava. sedimentary rock are types of rock that are formed by the deposition of material such as sand dead animals etc. at the earth's surface and within bodies of water. Metamorphic rock is the original rock subjected to heat and pressure, causing physical or chemical change. Mantle is the middle layer of the earth. The asthenosphere is the highly viscous, mechanically weak and de-shaped region of the upper mantle of the earth and it lies below the lithosphere.

This is what we have been learning in science and it's been pretty fun so far. Then we had a short 5 question pop quiz and it was not that big of a surprise apparently...l but overall science hasn't been bad and this is a easy subject right now because I understand most of it.
