DRAW IT (a) Draw a simplified global water cycle showingocean, land, atmosphere, and runoff from the land to theocean. Label your drawing with these annual water fluxes:ocean evaporation, 425 km3ocean evaporation that returns to the ocean as precipitation,385 km3ocean evaporation that falls as precipitation on land, 40 km3evapotranspiration from plants and soil that falls as precipitation on land, 70 km3runoff to the oceans, 40 km3(b) What is the ratio of ocean evaporation that falls as precipitationon land compared with runoff from land to the oceans? (c) Howwould this ratio change during an ice age, and why?

Physical and Chemical features

The physical property of a compound could be determined without modifying the originality of the compound. Examples of physical properties are density, hardness, color, boiling, and melting point. The chemical property expresses the ability of a compound to undergo a particular chemical change.
