Description

"Water Cycle" Water on Earth PPT

Part One: Teaching Objectives

1. The process and main links of the water cycle.

2. The geographical significance of the water cycle.

Water cycle PPT, part 2: water cycle

The water cycle refers to the process of continuous movement of natural water through various links in the four major spheres of hydrosphere, atmosphere, lithosphere and biosphere.

Types of water cycle: circulation between sea and land, circulation within land, circulation within ocean

Water cycle power: solar radiation, gravity, etc.

circulation between sea and land

The circulation between sea and land refers to the mutual conversion movement between ocean water and land water through a series of processes. This cycle is also called a large cycle.

intraterrestrial circulation

Some or all of the water that falls on the continent (referring to the inward flow area) forms water vapor through the evaporation of the land surface, water surface and plant transpiration. It is carried upward by the air flow, cools and condenses to form precipitation, and still falls on the continent. This is the internal flow of the land. cycle.

internal circulation at sea

The water on the ocean surface evaporates to form water vapor, which enters the atmosphere and condenses over the ocean to form precipitation, which then falls to the sea surface.

Water cycle PPT, part three: activity exploration

—Understand the water cycle aspects affected by sand fields

Analyze the impact of sand and gravel on water infiltration

Compare the difference in evaporation between sand fields and bare fields to illustrate the impact of sand and gravel cover on evaporation

Read textbook Figure 3.5, compare the soil moisture content of sand fields and bare fields at the end of April, and summarize the water cycle links and functions affected by sand fields.

Water cycle PPT, part 4: geographical significance of the water cycle

The water cycle keeps various water bodies on the earth in a state of constant renewal and maintains the dynamic balance of global water.

The water cycle is one of the most active energy exchange and material transfer processes on Earth.

The water cycle is the most dynamic cyclic movement in nature, constantly sculpting the surface form.
