Which of the following landforms is formed by glacial deposition and is characterized as an elongated, streamlined, teardrop-shaped hill of unsorted till with its blunt end pointing towards the direction of ice advance?
In arid regions, wind action causes severe erosion through different mechanics. Which landform is created when wind abrasion selectively undercuts the base of a rock outcrop more rapidly than its top due to sand particles being carried close to the ground?

In a glaciated mountain region, a massive main-trunk glacier erodes its valley far deeper than smaller feeder glaciers. Upon deglaciation, the tributary valleys remain perched high above the main trough floor, typically featuring plunging waterfalls. Which landform does this description represent?

In an arid environment, wind deflation selectively removes loose, fine-grained sediments until a continuous armor of polished, coarse pebbles covers the desert floor. In contrast, in areas where wind abrasion attacks alternating horizontal strata of hard and soft rocks near the surface, deep parallel furrows are gouged out, leaving standing ridges of resistant rock. Which pair of aeolian features describes these respective erosion landforms?
Arrange the following stages in the development of a desert oasis resulting from wind action in the correct sequential order from earliest to latest.

A field geologist observes a glaciated bedrock feature characterized by a smooth, gently inclined side facing the direction of ice advance and a steep, jagged slope on the down-flow side. Which landform and primary evolutionary process are described?
During glacial retreat, unsorted and unstratified rock debris carried by a glacier is deposited directly by the melting ice to form ridges along the edges and snout of the glacial valley. Which of the following landforms is formed by this process?
In glaciated highland regions, frost action and glacial movement progressively transform mountain slopes into distinctive alpine landforms over time. Arrange the following geomorphic stages in the correct chronological order of their evolutionary sequence, from the initial process to the final landform.

In arid regions, mushroom rocks (pedestal rocks) typically exhibit a narrow, undercut base beneath a broader cap rock. Which geomorphic factor explains why wind abrasion is most severe within the lowest one meter of the rock structure?
