The water cycle has no starting point. But, we'll begin in the oceans, since that is where most of Earth's water exists. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates<span> as vapor into the air. Ice and snow can </span>sublimate<span> directly into water vapor. Rising air currents take the vapor up into the </span>atmosphere<span>, along with water from </span>evapo-transpiration<span>, which is water transpired from plants and evaporated from the soil. The vapor rises into the air where cooler temperatures cause it to </span>condense<span> into clouds. Air currents move clouds around the globe, cloud particles collide, grow, and fall out of the sky as </span>precipitation<span>. Some precipitation falls as snow and can accumulate as </span>ice caps and glaciers<span>, which can store frozen water for thousands of years. Snow packs in warmer climates often thaw and melt when spring arrives, and the melted water flows overland as </span>snow melt<span>. Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as </span>surface runoff<span>. A portion of runoff enters rivers in valleys in the landscape, with </span>stream flow<span> moving water towards the oceans. Runoff, and groundwater seepage, accumulate and are </span>stored as freshwater<span> in lakes. Not all runoff flows into rivers, though. Much of it soaks into the ground as </span>infiltration<span>. Some water infiltrates deep into the ground and replenishes </span>aquifers<span> (saturated subsurface rock), which store huge amounts of freshwater for long periods of time. Some infiltration stays close to the land surface and can seep back into surface-water bodies (and the ocean) as </span>groundwater discharge<span>, and some ground water finds openings in the land surface and emerges as freshwater </span>springs<span>. Over time, though, all of this water keeps moving, some to reenter the ocean, where the water cycle "ends" ... oops - I mean, where it "begins." Hope this helped!!</span>

Explanation:
Answer:
Different ideological orientations and forms of nationalism exist. It comes from both the left and the right, and it has historically been associated with a variety of social movements. It was associated with right-wing, even fascist tendencies in the 1920s, 1930s, and 1940s. However, in developing countries, it has allied with left-wing communist movements as well as anti-imperialist and anti-colonial movements. Nationalism isn't a political color in and of itself.It's critical to reclaim some of the advantages of national identification. National identities can foster a sense of community and motivate people to work together for a common good. Governments with a strong sense of national identity can more easily redistribute resources and build welfare states. These countries' citizens are less averse to paying taxes.
