Atmospheric heating process and atmospheric movement PPT, part 2 content: independent preview to explore new knowledge

1. The heating process of the atmosphere

1. Energy source: _______.

2. Direct heat source: _______ is the main, direct heat source of the atmosphere near the ground.

3. Heating process

Specific process results

ground increase

Temperature process Most of the A_____ reaches the ground through the atmosphere and heats the ground

Increased atmosphere

Temperature process After the ground is heated, heat is transferred to the atmosphere near the ground in the form of B_____, causing _____ to become warmer.

2. The thermal insulation effect of the atmosphere on the ground

1. Atmospheric longwave radiation:

Water vapor, carbon dioxide, etc. in the troposphere strongly absorb _____ long-wave radiation and increase their temperature, producing atmospheric _____ radiation.

2. Atmospheric reverse radiation: The portion of atmospheric radiation that shoots downward toward _____.

3. Insulation effect: Atmospheric reverse radiation transfers _____ to the ground, compensating for the heat lost by _____.

[Special Reminder]

1. The atmosphere weakens solar radiation: Some components and phenomena in the atmosphere absorb, reflect and scatter solar radiation, thus weakening the solar radiation reaching the ground to a certain extent.

2 Atmospheric reverse radiation is a part of atmospheric radiation that always exists during the day and night, and the radiation is stronger during the day.

The heating process and insulation effect of the atmosphere

On November 19, 2018, on the occasion of the 20th anniversary of the establishment of the International Space Station, the chief designer of the Russian Federal Space Agency announced to the outside world that in 2030, Russian astronauts will achieve the first lunar landing and are expected to stay on the moon for 14 days. Immigrating to the moon has always been a dream of mankind, but the "lunar immigration" that is hotly discussed among the people is still difficult. This is because the temperature difference between day and night on the moon's surface is very large. During the day, the temperature in places where sunlight shines vertically is as high as 127°C; at night, the temperature can drop to -183°C.

Question 1 (Geographical Practical Ability) Please mark solar radiation, absorption (atmosphere to sun), reflection (atmosphere to sun), ground radiation, and atmospheric inverse radiation at appropriate locations in the figure below.

Question 2 (Comprehensive thinking) Why do the temperatures on the moon change so drastically?

Tip: There is no atmosphere on the moon, so day and night temperatures cannot be adjusted.

Question 3 (Comprehensive thinking) The earth, moon and sun are at the same distance. Why is the temperature on the earth relatively stable?

Tip: There is an atmosphere on the earth. During the day, the atmosphere weakens solar radiation, reducing the solar radiation reaching the ground and causing the temperature to rise slowly. At night, the atmospheric reverse radiation has a thermal insulation effect on the ground, causing the ground temperature to drop slowly.

[Summary]

1. The weakening effect of the atmosphere on solar radiation

(1) Absorption: The atmosphere absorbs very little visible light with the strongest energy. As shown below:

Atmospheric absorption of solar radiation

(2) Reflection: Clouds and larger dust have a more obvious reflection effect on solar radiation, and the reflection effect of clouds is the most significant. As shown in the picture:

Geographic practice: observing greenhouse production in agricultural production

Greenhouse, also known as greenhouse. A facility that can transmit light, retain heat (or heat), and is used to cultivate plants. In seasons that are not suitable for plant growth, it can provide a greenhouse growth period and increase output. It is mostly used for the cultivation or seedling cultivation of warm-loving vegetables, flowers, forest trees and other plants in low-temperature seasons. There are many types of greenhouses, which can be divided into many types according to different roof truss materials, lighting materials, shapes and heating conditions.

Using the principle of the "greenhouse effect", greenhouses can be used to grow vegetables, flowers and other crops in winter in northern my country. The picture below is a landscape map of agricultural production in plastic greenhouses. Answer questions (1) to (2) accordingly.

(1) Which of the following does not belong to the impact of greenhouse technology on agricultural production ()

A. It is conducive to making full use of solar energy and increasing the temperature in the greenhouse.

B． Helps increase light intensity and enhance crop photosynthesis

C． Helps maintain and regulate the humidity of the air in the greenhouse

D． Helps maintain and regulate soil moisture in the greenhouse

(2) When the door of the greenhouse is opened, the air flow at the door is the same as the air flow shown in the figure below ()

(1)B　(2)A　For question (1), light intensity is mainly related to solar radiation intensity. Greenhouse technology cannot increase light intensity. Question (2): The temperature inside the greenhouse is high and the temperature outside is low. After the door is opened, a thermal circulation is formed inside and outside the door. The warm air inside flows to the outside above the door, and the cold air outside flows to the room at the bottom of the door. ]

Atmospheric Heating Process and Atmospheric Movement PPT, Part 5 Content: Literacy Standards and Solid Basics

1. The sequence of heat transfer processes that increase the temperature of the atmosphere near the ground is ()

A. ①—②—③ B． ①—④—②

C． ②—③—④ D. ③—④—②

2. The atmospheric temperature near the ground decreases with increasing height, and the influencing factors are arrows ()

A. ① B． ②

C． ③D. ④

1.B　2.B　[Question 1, the process of atmospheric warming near the ground is that most of the ① solar radiation passes through the atmosphere and reaches the ground. After the ground is heated, it transfers heat to the atmosphere in the form of ② ground radiation. The atmosphere absorbs radiation from the ground and heats up. Question 2: The direct and main heat source of the atmosphere near the ground is ② ground radiation. ]

3. There is a saying in meteorological proverb that "the sky is clear when the dew is heavy". Regarding this phenomenon, which of the following statements is correct ()

A. There are few clouds in the sky and the atmosphere has strong thermal insulation effect.

B． Ground radiation is strong and the surface cools slowly

C． There is less water vapor in the air and the surface cools slowly.

D． Atmospheric reverse radiation is weak and the surface cools quickly
