Mountains resistant to erosion.

|
Only top layer of rock would be eroded.

Detailed explanation-1: -Hilly landscapes Regions where the strata have a similar or equal resistance to erosion results in hills with steep rounded slopes. These regions typically have high rainfall, with the water eroding and smoothing the hills creating domed peaks.
Detailed explanation-2: -Horizontally layered rocks refer to sedimentary rocks as they are layered. Sedimentary rocks form from deposits of sediment that are built up in a series of layers on the sea floor. Parallel layers of sedimentary rocks are called beds or strata.
Detailed explanation-3: -Hills are also formed because of erosion, which happens when bits of rock, soil, and sediment get washed away and placed in a pile somewhere else. Hills can be destroyed by erosion, as material is worn away by wind and water.
Detailed explanation-4: -Layered igneous rocks (flows and sills) are generally more resistant than sedimentary rocks because of their low porosity.
