Geography flashcards for ICSE Class 9
25 of 51 cards from the Geography deck — real questions with worked answers.
What is the shape of the Earth called, and what does the term mean?
The Earth's shape is called a geoid (or oblate spheroid) — slightly flattened at the poles and bulging at the equator, not a perfect sphere.
What are the equatorial and polar diameters of the Earth?
Equatorial diameter is about 12,756 km; polar diameter is about 12,714 km — a difference of roughly 42 km.
Define rotation of the Earth and state the time it takes.
Rotation is the spinning of the Earth on its own axis from west to east; it completes one rotation in about 23 hours 56 minutes (taken as 24 hours), causing day and night.
Define revolution of the Earth and state its duration.
Revolution is the movement of the Earth around the Sun in an elliptical orbit; it takes 365¼ days (one year), causing the seasons.
What is the angle of inclination of the Earth's axis, and why is it important?
The Earth's axis is inclined at 23½° to the perpendicular of its orbital plane (66½° to the orbital plane). This tilt, combined with revolution, causes the seasons.
What is a leap year and why does it occur?
A leap year has 366 days, occurring every 4 years. The extra ¼ day from each year's revolution (365¼ days) accumulates to one full day added to February (29 days).
What are the latitudes of the Tropic of Cancer, Tropic of Capricorn, and the two Polar Circles?
Tropic of Cancer: 23½°N; Tropic of Capricorn: 23½°S; Arctic Circle: 66½°N; Antarctic Circle: 66½°S.
What is the Prime Meridian and what is its longitude?
The Prime Meridian is 0° longitude, passing through Greenwich (London). It is the reference line for measuring longitude and for calculating standard time.
How is the Earth's circumference divided to make time zones, and how much time does 1° of longitude represent?
The Earth turns 360° in 24 hours, so 15° of longitude = 1 hour, meaning 1° of longitude = 4 minutes of time.
What is the longitude of the Indian Standard Time (IST) meridian, and how far ahead of GMT is India?
IST is based on 82½°E longitude; India is 5 hours 30 minutes ahead of GMT (Greenwich Mean Time).
What are the three main layers of the Earth's interior?
The crust (outermost, thin), the mantle (middle, mostly solid silicate rock), and the core (innermost, made mainly of iron and nickel, with a liquid outer and solid inner part).
Name the three main types of rocks based on their mode of formation.
Igneous rocks (formed from cooled magma/lava), Sedimentary rocks (formed from compacted sediments), and Metamorphic rocks (formed when existing rocks change under heat and pressure).
Give one example each of igneous, sedimentary and metamorphic rock.
Igneous: granite or basalt; Sedimentary: sandstone or limestone; Metamorphic: marble (from limestone) or slate (from shale).
What is the difference between a fold mountain and a block mountain?
A fold mountain forms when crustal layers are compressed and folded upward (e.g., Himalayas). A block mountain (horst) forms when land between two faults is uplifted or the surrounding land sinks (e.g., Vosges, Black Forest).
What is weathering, and how does it differ from erosion?
Weathering is the breaking down of rocks in place by physical, chemical or biological agents. Erosion is the wearing away AND removal/transport of the broken material by agents like rivers, wind, glaciers and waves.
Name the three stages of a river's course and one landform of each.
Upper (youthful) course — V-shaped valley/waterfall; Middle (mature) course — meanders; Lower (old) course — delta/floodplain.
How is a delta formed?
A delta forms at a river's mouth when the river deposits its sediment load as it loses speed entering a sea or lake, building up triangular low-lying land (e.g., the Ganga-Brahmaputra Delta).
What is a glacier and name two landforms it creates by erosion?
A glacier is a slowly moving mass of ice. Erosional landforms include U-shaped valleys, cirques, arêtes and horns.
Name two depositional landforms made by wind in deserts.
Sand dunes and loess (fine wind-deposited soil) are depositional landforms created by wind.
What is the hydrosphere?
The hydrosphere is all the water on Earth — oceans, seas, rivers, lakes, groundwater, glaciers and water vapour in the atmosphere.
Approximately what percentage of the Earth's surface is covered by water, and what fraction of that is fresh water?
About 71% of the Earth's surface is water; only about 2.5–3% of all water is fresh water, and most of that is locked in glaciers and ice caps.
Name the four major oceans of the world in order of size.
Pacific Ocean (largest), Atlantic Ocean, Indian Ocean, and Arctic Ocean (smallest). (The Southern/Antarctic Ocean is now also recognised.)
What are ocean currents and how are warm and cold currents different?
Ocean currents are large-scale movements of seawater in fixed directions. Warm currents flow from the equator toward the poles; cold currents flow from the poles toward the equator.
What are tides and what causes them?
Tides are the periodic rise and fall of sea level, caused mainly by the gravitational pull of the Moon (and Sun) on the ocean waters.
Differentiate between spring tides and neap tides.
Spring tides are the highest tides, occurring at full and new moon when Sun, Moon and Earth are aligned. Neap tides are the lowest tides, occurring at first and third quarter when Sun and Moon are at right angles to Earth.
Planning Geography for ICSE Class 9
Geography is about 16% of the ICSE Class 9 syllabus by topic count — 8 of 49 topics, spread over 1 chapters. At roughly 45 minutes per topic plus 12 minutes per sub-topic, a first pass runs to about 6 hours.
Work top-down: read the chapter, then tick topics off individually rather than marking the whole chapter done. Sub-topics are where silent gaps hide.
