Part One Content: Learning Objectives:

1. Analyze and illustrate the impact of latitude factors, land and sea factors, and topographic factors on climate with examples.

2. Read various maps, landscape pictures, written materials, etc., extract information, and analyze the causes of climate differences in different regions.

Learning points:

The impact of three major factors on climate.

think?

What are the factors that affect climate?

1.Latitude factor 2.Sea and land factor 3.Topography factor

PPT on the main factors forming climate, part 2: influencing factors

1. Latitude factor

Independent learning Warm reminder: Read the text on page 79

_______ factors are the basic factors that form climate. Generally speaking, places with latitudes higher than _______ receive more solar heat and have higher temperatures. Places with latitudes higher than _______ receive less solar heat and have lower temperatures. Therefore, people divide the earth's surface into _______ zones, _______ zones, and _______ zones

Collaborative exploration: Thinking: What is the reason for the difference in climate between places A and B?

Conclusion: The earth is a sphere, and places at different latitudes receive different amounts of solar heat, resulting in significant differences in temperature and precipitation between high and low latitudes.

1. Impact on temperature: The higher the latitude, the lower the temperature; the lower the latitude, the higher the temperature.

2. Impact on precipitation: There is more precipitation in the equatorial regions and less precipitation in the polar regions.

2. Sea and land factors

Self-learning

Read 80 pages of the text and complete the following with the help of pictures:

1 Water vapor on land mainly comes from ________. Therefore, areas that are close to the ocean and can be affected by ocean moist airflow generally have _______ precipitation. Inland areas far away from the ocean generally have _______ precipitation.

2 The properties of oceans and land are different, and the conditions of heat absorption and heat dissipation are also different. Land heats up _______ and cools down _______, and the opposite is true for the ocean. Therefore, at the same latitude, the temperature of _______ is higher than _______ in summer; the opposite is true in winter.

Consolidate and improve

Comparison between Turpan and Qinhuangdao in summer:

1. Where is it hotter? Why?

2. Which place has more precipitation compared to the two places? Where does it rain less?

3. Topographic factors

1. Impact on temperature

Generally speaking, for every 1,000 meters of altitude increase, the temperature drops by 6°C.

2. Impact on precipitation

Why does place A have more precipitation and place B has less precipitation?

Site A is located on the windward slope of the Andes Mountains, while Site B is located on the leeward slope of the Andes Mountains.

Summary: The impact of land and sea factors on climate

1. Comparing areas with the same latitude, the higher the altitude, the lower the temperature; the lower the altitude, the higher the temperature. For every 1000 meters of altitude increase, the temperature decreases by 6ºC

2. Windward slopes receive more precipitation; leeward slopes receive less precipitation.

PPT on the main factors forming climate, part three: detection feedback

1. The two elements of climate are ______ and ______.

2. What are the factors that affect climate?

3. The main reason for "the beauty of April in the world is exhausted, and the peach blossoms in the mountain temple begin to bloom" is ( )

A.Latitude factor B.Sea and land factor

C. Topographic factors D. Ocean current factors

PPT on the main factors forming climate, part 4: What impact do human activities have on climate?

Improve the local environment:

Artificial greening, water conservancy construction,

Build ecological protection forest

Destroy the natural environment:

Indiscriminate cultivation, overgrazing
