"Natural Environment" The Continent We Live in - Asia PPT Courseware

Question: How to describe the natural environment of an area? What aspects are included?

1. Features such as topography, topography, rivers, and climate

2. The influence of topography and topography on rivers and climate

Summarize the topographic characteristics of Asia:

1. The ground in Asia is highly undulating, with high levels in the middle and low levels on all sides.

2. The terrain is complex and diverse, mainly plateaus and mountains.

Find the major terrain areas of North America

1. Find the Coast Mountains, the Sierra Nevada, the Rockies, the Great Plains, the Mississippi River Plain, the Labrador Plateau, and the Appalachian Mountains. Indicate their locations and approximate elevations in North America.

2. According to the principle of "relative consistency and spatial continuity", North America is divided into three regions according to terrain: western, central and eastern regions. Name the main terrain types in these three regions.

The west is mainly mountainous, the central part is plain, and the east is mountainous and plateau.

Using the Mississippi River as an example, explain the impact of North America's topography on river flow.

1. Find the Mississippi River and its main tributaries in the diagram and mark their flow directions with arrows.

2. Analyze the relationship between the flow direction of these rivers and the terrain.

Because the east and west parts of North America are higher mountains and plateaus, the middle part is low-lying plains, and the southern part is even lower. Rivers originate in the east and west, flow to the middle, and eventually flow south into the ocean.

Question: What are the characteristics of Asia’s climate? What are the causes of these climate characteristics?

Summarize the characteristics of Asia’s climate:

1. Complex and diverse climate types

2. Continental climate is widely distributed

3. Significant monsoon climate

Why does the Asian climate have such characteristics?

Asia has a wide latitude and spans tropical, temperate and frigid zones. It is bordered by the ocean on three sides in the east, north and south. Its central and western parts are deep in the hinterland of the Eurasian continent. There are obvious thermal differences between the sea and the land, and the terrain is complex and diverse.

Understand the distribution of climate in North America

1. Identify the main climate types in North America; indicate the most widespread climate type in North America and state its distribution range.

The most widespread is temperate continental climate, mainly found within continents.

2. Find the 40° north latitude line and name the climate types it passes through from west to east.

Mediterranean climate, plateau mountain climate, temperate continental climate, subtropical humid climate.

3. Find the longitude 80° West and name the climate types it passes through from north to south.

Cold zone climate, temperate continental climate, subtropical humid climate, savanna climate, tropical rainforest climate.

To sum up, the climate characteristics of North America are summarized as follows:

Temperate continental climate has a wide distribution and diverse climate types.

Read Figure 6.13 and answer:

1. Asia’s largest area has a ________ climate. The climate with the most precipitation is _________.

2. The Tropic of Cancer passes through ________ climate, ________ climate and ________ climate from east to west.

3. Along the 116°E meridian from south to north, we pass through ________ climate, ________ climate, ________ climate, ________ climate and ________ climate.

4. East and south Asia are affected by ________ and are prone to ________ disasters.

5. What types of monsoon climate are there in Asia?

Tropical monsoon climate, subtropical monsoon climate, and temperate monsoon climate.
