Which of the following statements are concerned with eskers and drumlins?
- Eskers are ridges of crudely bedded gravels and sands.
- Drumlins are constituted mostly of boulder and clay.
- Basket of eggs topography is the characteristic of terrains with eskers
- While eskers are built by glacier streams, drumlins result from glacier action.
Choose the correct answer from the options given below.
Detailed Explanation:
Eskers are sinuous ridges formed by glacial meltwater streams, composed of crudely bedded gravels and sands (Statement 1 correct). Drumlins are streamlined hills formed by direct glacial action, consisting mainly of boulder clay/till (Statement 2 correct). Statement 4 correctly distinguishes their formation: eskers by subglacial streams, drumlins by moving ice.
Statement 3 is incorrect: "Basket of eggs topography" characterizes terrain with drumlins, not eskers. Drumlin fields resemble baskets of eggs when viewed from above due to their oval, clustered appearance.
Therefore, statements 1, 2, and 4 are correct, making Option 2 the correct answer.
Which of the following planets has the least density?
Detailed Explanation:
Saturn has the lowest density of all planets at approximately 0.687 g/cm³—less than water (1 g/cm³). Its composition is primarily hydrogen and helium gases with a small rocky core, making it extremely light relative to its volume.
Earth (5.52 g/cm³), Venus (5.24 g/cm³), and Mars (3.93 g/cm³) are terrestrial planets with dense metallic cores and rocky surfaces, resulting in significantly higher densities.
Therefore, Saturn has the least density, making Option 4 the correct answer.
Which of the following countries does not have a land border with the Dead Sea?
Detailed Explanation:
The Dead Sea is bordered by only two countries: Jordan (east) and Israel (west and south). The West Bank (Palestine) also touches its western shore between Israeli territory.
Lebanon lies far to the north and shares no border with the Dead Sea. Since Option 1 (Lebanon) is the only correct individual answer, and it appears among the options, the question's logic points to Option 5.
Therefore, Lebanon does not border the Dead Sea, making Option 5 the correct answer.

An effective Coriolis force results from
Detailed Explanation:
The Coriolis force is an apparent deflection of moving objects (air, water, projectiles) caused by the Earth's rotation. It acts perpendicular to the direction of motion and the axis of rotation, influencing wind patterns, ocean currents, and cyclone formation.
The solar system and Earth's interior do not generate this effect, and ocean currents like the Colorado and Gulf Streams are themselves influenced by the Coriolis force, not its cause.
Therefore, Earth's rotation is the sole cause of the Coriolis force, making Option 2 the correct answer.
Sunda Trench lies parallel to the island of
Detailed Explanation:
The Sunda Trench is a deep oceanic trench in the Indian Ocean that runs parallel to the Indonesian island arc. It extends along both Java and Sumatra, forming part of the Sunda Arc subduction zone where the Indo-Australian Plate slides beneath the Eurasian Plate.
Maldives and Mauritius are isolated island groups in the Indian Ocean, far from any major tectonic trenches and unrelated to the Sunda system.
Therefore, since the Sunda Trench parallels both Java and Sumatra (more than one option), Option 5 is the correct answer.
The theory of continental drift was developed by
Detailed Explanation:
Alfred Wegener (1912) proposed the Theory of Continental Drift, suggesting that continents were once part of a supercontinent Pangaea and drifted apart over geological time.
J. J. Wilson contributed to plate tectonics, Du Toit supported Wegener's theory with evidence from Gondwanaland, and H. Hess developed seafloor spreading theory—but none originated the drift hypothesis.
Therefore, A. Wegener developed the continental drift theory, making Option 2 the correct answer.
Geodesy is the science that deals with
Detailed Explanation:
Geodesy is the Earth science dealing with the measurement and representation of Earth's shape, size, and dimensions, including its gravitational field and orientation in space.
Option 1 refers to geochronology, Option 3 to topography/hypsometry, and Option 4 to tectonics/geology—none define geodesy's core function of measuring Earth's dimensions.
Therefore, geodesy's primary focus on Earth's measurement makes Option 2 the correct answer.
