Description

"Karst, Coastal and Glacier Landforms" Earth Surface Form PPT Courseware

Part One Content: Curriculum Standards:

Through field observation or the use of videos and images, identify 3 to 4 types of landforms and describe the main characteristics of their landscapes.

Literacy goals:

1. Identify common karst landforms, coastal landforms and glacial landforms through field observation or use of images. (Regional awareness, geographical practice)

2. Be able to describe the landscape characteristics of common karst landforms based on landscape pictures or diagrams. (comprehensive thinking)

3. Be able to simply analyze the relationship between karst landforms and other physical geographical elements, and their interaction with human activities. (Coordinated view of man and earth, comprehensive thinking)

Karst Coast and Glacier Landform PPT, Part 2 Content: Essential Knowledge and Literacy Foundation

1. Karst landforms

2. Coastal landforms

1. Coastal landforms: The coastal zone is affected by tectonic movements, ________, and biological processes.

Surface morphology formed under the combined action of climate factors and other factors.

2. Main types:

(1) Sea erosion landforms: A_______, B_________, C_______.

(2) Marine landforms: Ding_____, sand spits, offshore embankments, underwater sand bars, etc.

3. Glacial landforms

1. Concept: Landforms formed by ________ changes caused by glaciation.

2. Type: Common glacial landforms include _____, glacial troughs (U-shaped valleys), horn peaks and blade ridges, etc.

3. Distribution: Glacier landforms are mainly distributed in _____ areas and mid- to low-latitude alpine areas.

[Question] Are the landforms formed by glaciers in different areas the same?

Tip: It is different. The upper part of the mountain erodes to form cirques, horn peaks, etc., and the accumulation at the bottom of the mountain forms moraine hills, moraine lakes, etc.

Karst Coast and Glacier Landform PPT, Part 3: Key Abilities·Quality Formation

Capability: The formation process of karst landforms and coastal landforms

1. Karst landform:

(1) Development process.

(2) The formation process of karst landform landscape.

Karst landforms have different landscapes on the surface and underground, with different shapes and causes. The specific analysis is as follows.

2. Coastal landforms:

(1) Coastal erosion landforms.

(2) Coastal accumulation landforms.

[Typical example demonstration]

On September 25, 2016, FAST, the world's largest spherical radio telescope, was completed and opened in the "Dawodang" karst depression in Pingtang, Guizhou. The picture below is a "schematic diagram of the geological conditions at different stages during the formation of karst depressions." Complete the next question accordingly.

The geological process of forming karst depressions, the correct sequence is ()

A.②①③④

B.②①④③

C.④③②①

D.④①③②

[Ideas] To solve this kind of problem, you should start from the following two points:

(1) Clarify the causes and processes of the formation of karst depressions, and the process in which limestone layers are intensified by dissolution by flowing water.

(2) Observe the formation process diagram: Judge the formation process based on the size and collapse conditions of the underground cave in the picture.

[Analysis] Choose B. The formation of karst depressions changes from small to large, and from underground to open air. ② Figure forms a small cave underground, ① Figure the underground cave becomes larger, ④ Figure the top of the cave collapses, ③ Figure karst depression forms and expands.

【Compensation training】

(2019·Tianjin Grade 1 Test) The picture below shows the profiles of peak clusters, peak forests and solitary peaks in a certain place in my country. Based on this, you can complete questions (1) and (2).

(1) The topography and landforms represented in the figure are mainly distributed in ()

A. Basalt distribution area

B. Limestone distribution area

C.Marble distribution area

D. Granite distribution area

(2) There are three types of mountainous landforms marked in the picture, and the order of their formation is ()

A. Fengcong → Gufeng → Fenglin B. Fengcong → Fenglin → Gufeng

C. Gufeng → Fengcong → Fenglin D. Fenglin → Gufeng → Fengcong

[Analysis] (1) Choose B, (2) Choose B. Question (1): Karst landforms are mostly developed in areas where limestone is widely distributed. For question (2), according to the evolutionary sequence from left to right in the figure, it can be seen that the evolutionary sequence of the three landforms is peak cluster → peak forest → isolated peak.

【Literacy Research】

In November 2016, Shaanxi Province discovered a large-scale sinkhole group in Hanzhong. This is the northernmost tiankeng group found in the subtropical karst areas of mainland my country. The picture below is a schematic diagram of the formation process of a collapsed sinkhole.

(Comprehensive thinking) According to the diagram, describe the geological process of the formation of a collapsed sinkhole.

Tip: The limestone was first dissolved and eroded by groundwater to form a cave. Later, the rock layer above the cave collapsed multiple times and was exposed to the ground to form a sinkhole.
