Answer: (d)
Answer: (d)
Answer is Option A. -> throws water and steam at regular intervals
Answer: (a) A geyser is a spring characterized by intermittent discharge of water ejected turbulently and accompanied by a vapour phase (steam). The word geyser comes from Geysir, the name of an erupting spring at Haukadalur, Iceland; that name, in turn, comes from the Icelandic verb geysa, “to gush”, the verb itself from Old Norse.

Answer is Option A. -> Cave
Answer: (a) Cliffs, caves, arches, stacks are some of the landforms produced by wave erosion. Coves form where rock runs in bands horizontal to the direction of wave attack. There is a band of resistant rock closest to the sea and a band of less resistant rock inland. The waves seek out faults in the hard rock and erode using the processes of abrasion/corrosion and hydraulic action through to the soft rock behind.

Answer is Option B. -> smooth curve from source to mouth.
Answer: (b) The course of a river from its source to its mouth is normally divided into 3 sections, namely upper, middle and lower courses. The action of the river on its valley from source to mouth in relation to the features developed by it is seen in the river valley profile, known as a graded profile. Throughout the long profile of a river, deposition and erosion are balanced meaning that, given enough time, the river’s long profile would become a smooth, concave, graded profile from its source to mouth.

Answer is Option C. -> Fiords
Answer: (c) Geologically, a fjord is a long, narrow inlet with steep sides or cliffs, created in a valley carved by glacial activity. A fjord is formed when a glacier cuts a U-shaped valley by ice segregation and abrasion of the surrounding bedrock. Glacial melting is accompanied by the rebound of Earth's crust as the ice load and eroded sediment is removed. Both the whole coast of Norway and the island of Greenland have many fjords.

Answer is Option D. -> imaginary line passing round the Earth midway between North & South poles
Answer: (d) An equator is the intersection of a sphere’s surface with the plane perpendicular to the sphere’s axis of rotation and containing the sphere’s center of mass. Notably, the Equator refers to the Earth’s equator, per above: an imaginary line on the Earth’s surface equidistant from the North Pole and the South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. Other planets and spherical astronomical bodies have equators similarly defined. The length of the Equator is roughly 40,075 kilometers.

Answer is Option B. -> 1 only
Answer: (b)Creep is the imperceptibly slow, down slope movement of soil and earth materials.
Answer: (b)Creep is the imperceptibly slow, down slope movement of soil and earth materials.
Answer is Option B. -> I, II and III
Answer: (b)Earthquakes are caused by faulting, a sudden lateral or vertical movement of rock along a rupture (break) surface. Earthquakes often occur in volcanic regions and are caused there, both by tectonic faults and the movement of magma in volcanoes.Such earthquakes can serve as an early warning of volcanic eruptions, as during the Mount St. Helens eruption of 1980.

Answer is Option A. -> South America
Answer: (a)
Answer: (a)
Answer is Option C. -> 1, 2, 3 and 4
Answer: (c)The most powerful agents of marine or coastal erosion are waves. Features associated with coastal erosion are capes and bays; cliffs and wave-cut platforms; cave, arch, stack and stump; goes and gloups.
