Q: Q: What is the earths crust composed of? Read this paragraph and choose the correct option from the provided answers: Like Earth, the Moon has a distinct crust, mantle, and core. The crust is composed of igneous rock. This rock is rich in the elements oxygen, silicon, magnesium, and aluminum. On the near side, the Moon's crust is about 30 kilometers thick. On the far side, the crust is about 100 kilometers thick. The mantle is made of rock like Earth's upper mantle. The Moon has a small metallic core, perhaps 300 to 500 kilometers in diameter. The composition of the core is probably mostly iron with some sulfur and nickel. We learned this both from the rock samples gathered by astronauts and from spacecraft sent to the Moon. Choices: - sedimentary rock - bicellular rock - metamorphic rock - igneuos rock A:
A: igneuos rock

Q: Q: What is the term for a mixture of two or more substances that has the same composition throughout? Read this paragraph and choose the correct option from the provided answers: Water is the main ingredient of many solutions. A solution is a mixture of two or more substances that has the same composition throughout. Some solutions are acids and some are bases. To understand acids and bases, you need to know more about pure water. In pure water (such as distilled water), a tiny fraction of water molecules naturally breaks down to form ions. An ion is an electrically charged atom or molecule. The breakdown of water is represented by the chemical equation. Choices: - fluid - simple liquid - structure - solution A:
A: solution
