Explain what is meant by the physical sciences. How are they different from life sciences? What disciplines make up the physical sciences? - Physical science studies non-living systems, as opposed to life science, which studies living systems. Physics, chemistry, and Earth and space sciences are all physical sciences. A scientist who studies how different sediments, rocks, and soil have formed the landscapes and natural structures that we see on Earth are included in the field of _______ - ...

Earth's outer core is liquid MOSTLY because of its - temperature Some large rivers, such as the MS River, form a delta where they meet the ocean, with land forming that extends into the sea. The formation of the delta is the result of erosion upstream where the flow is energetic and _____ where the flow is less rapid. - deposition Which type of rock is formed when sand, silt, clay, gravel, and cobbles become physically cemented or chemically fused together into hard rock? - Sedimentary Wh...

The details of how moving water flowing around an object such as a pebble can exert enough force to lift it and carry it. - physics The detailed mechanisms by which acidic pollutants in the river water change limestone, which does not dissolve, into partially soluble material, causing a large rock to weather? - chemistry The effect of weathering and erosion on features of the landscape over long periods of time. - Earth Science Comparison of the fin structures and their use in different sp...
