How can the Earth’s layers be illustrated?. Essential Questions:. Earth's Layers. Earth’s Crust. The outer layer of the Earth. The Sun. What physical features do you notice?. How does the Sun compare to the Earth and Moon?. What does the Sun provide for the Earth?. Physical Characteristics of the Sun. Sunspots. Solar Flare. Geological Time Scale. AIM: . How have stratigraphy and radiometric dating been used to construct the geological time scale?. The History of Earth. Earth’s history has been studied through 2 methods:. CONSERVİNG WATER. Conserve water at home. :. . Wasting water is one of the biggest ways individuals impact the health of the planet. Taking measures to use less water is something you can start doing right away. If you live in an area with a water shortage, this is even more important for the health of your region's environment. Try to check off as many items as possible from this list: . How does the atmosphere support life?. The atmosphere allows us to breathe. Many different types of organisms need oxygen to perform life processes. Plants require carbon dioxide to undergo photosynthesis. . determine. the Earth’s environment?. Does life simply live on an environmentally static Earth, or does life determine the Earth’s environment?. If life changes on the Earth, the conditions on Earth won’t change. Jun Wu and colleagues at Arizona State University have examined the issue broadly, considering planetary . accretion, magma . oceans, core formation, mantle convection, and interaction of a proto-atmosphere with the surrounding solar nebula. Their comprehensive hypothesis uses the isotopic composition of hydrogen as a tracer of the sources of water and its processing during planetary formation and subsequent differentiation. Here is an overview of their model in six stages. . The continuous movement of water . from the . ocean. …. to the . atmosphere. …. to the . land. …. and back to the . ocean.

Hard , solid, and strong. Cooler than other layers. Thinner beneath the oceans and made of basalt. Thicker beneath the continents and made of granite. The Mantle. Composed of two layers: the upper mantle and lower mantle. 97.5% of all water on Earth is salt water, leaving only 2.5% as fresh water . Nearly 70% of that fresh water is frozen in the icecaps of Antarctica and Greenland; most of the remainder is present as soil moisture, or lies in deep underground aquifers as groundwater not accessible to human use. .
