class=\"wp-block-list has-large-font-size\">\n<li>The water cycle describes how water moves on Earth.<\/li>\n\n\n\n<li>It includes processes like <strong>evaporation<\/strong>, <strong>condensation<\/strong>, <strong>precipitation<\/strong>, and <strong>infiltration<\/strong>.<\/li>\n\n\n\n<li>Evaporation occurs when the sun heats water bodies, turning liquid into vapor.<\/li>\n\n\n\n<li>Condensation forms clouds as vapor cools and turns back into liquid.<\/li>\n\n\n\n<li>Precipitation happens when clouds release water as rain, snow, sleet, or hail.<\/li>\n\n\n\n<li>Infiltration refers to water soaking into the soil, replenishing groundwater.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity
