FOLD MOUNTAINS How are fold mountains formed?

FEATURES OF FOLD MOUNTAINS

1. IRREGULAR FOLDS IN FOLD

MOUNTAINS DUE TO UNEQUAL

PRESSURE

What does this image show

Which type of rocks have this feature? How are these rocks formed?

FEATURES OF FOLD MOUNTAINS

FEATURE 2: MOST OF THESE MOUNTAINS ARE CONSTITUTED OF SEDIMENTARY ROCKS FORMED DUE TO

DEPOSITION AND CONSOLIDATION OF SEDIMENTS IN SHALLOW OCEANS

FEATURES OF FOLD MOUNTAINS

3. FOLD MOUNTAINS

HAVE GREATER LENGTH BUT

COMPARATIVELY SMALL WIDTH

FEATURES OF FOLD MOUNTAINS

FEATURE IV: MOST FOLD MOUNTAINS ARE FOUND ON THE MARGINS OF CONTINENTS

FEATURE V : FOLD MOUNTAINS ARE ASSOCIATED WITH VOLCANIC ACTIVITY AND HAS MANY ACTIVE VOLCANOES

on one side. The part facing the plain is steep.

PLAINS

What are Plains

PLAINS

TYPES OF PLAINSPLAINS

STRUCTURAL EROSIONAL

DEPOSITIONAL

STRUCTURAL PLAINS

Formed due to uplift or subsidence of land

LOCATION OF THE GREAT PLAINS OF USA

ERROSIONAL PLAINS These plains are formed by agents of

erosion like River Wind Chemical weathering

TYPES OF EROSIONAL PLAINS

EROSIONAL PLAINS

Peneplains Glacial erosion Wind eroded

Karst plain

PENEPLAINS Landscapes in which almost all hills

have been worn down as a result of erosion

The word peneplains means almost a plain

PENEPLAINS

LORRAINE PLAIN IN FRANCE

LOCATION OF LORRAINE PLAIN

GLACIAL EROSION

These plains have rounded peaks and worn down ice scoured shield lands

Due to the action of the glacier the area gets worn down and the height is reduced.

GLACIAL EROSION

PLAINS OF GLACIAL EROSION

WIND ERODED PLAINS

KARST PLAINS

KARST PLAINS Due to chemical weathering the area

gets eroded and produces undulating topography.

This type of features are mostly found in limestone landscapes where chemical weathering takes place.

DEPOSITIONAL PLAINS These plains are caused due the

deposition of various agents such as River Wind Sea
