Distribution of temperature and inversion of temperature

Correct answer: A. (17^\circ C)

At two thousand metres temperature falls by (13^\circ C) so the answer is (17^\circ C). In exams remember to subtract temperature with height.

Correct answer: B. Temperature inversion

Temperature is increasing with height so this is inversion. In exams quickly identify cold below and warm above.

Correct answer: A. Continents become colder than oceans in winter

Land cools quickly in winter so colder isotherms shift southward. In exams understand January through land water contrast.

Correct answer: B. Land heats rapidly and forms high temperature area

Tourism can provide income for conservation, local employment and public interest, but a protected area is also a living habitat. Excessive visitors, noise, traffic, litter, construction and disturbance can stress animals and interfere with feeding, breeding, resting or movement. Therefore, income alone cannot be used as the measure of success. Tourism must remain within limits that protect the ecosystem and the quiet conditions wildlife needs.

Option A is correct because focusing only on tourism income can disturb the balance between economic use and conservation. The other choices incorrectly assume that wildlife and habitats cannot be harmed. Responsible tourism may require visitor limits, quiet zones, regulated routes, waste control and monitoring. The exam idea is sustainable tourism: use a protected area in a controlled way while maintaining its ecological functions and respecting wildlife behaviour.

Correct answer: B. Cold current can partly reduce low latitude heating

A cold current lowers local temperature and modifies latitudinal effect. In exams weigh opposing factors together.

Correct answer: B. Continental interior far from sea

Higher annual range indicates continentality. In exams study distance from sea and temperature range together.

Correct answer: A. Surface radiational cooling increases and air mixing decreases

Clear sky lets heat escape and calm air keeps layers separate. In exams remember both conditions for inversion together.

Correct answer: B. Inversion separates the cold surface layer from upper winds

Inversion acts like a stable lid and isolates surface air. In exams distinguish calm surface air from upper winds.

Correct answer: A. Land water temperature contrast and ocean current

Bending of isotherms near coast may be linked with sea and current effects. In exams find physical causes behind map patterns.

Correct answer: B. Concrete asphalt less vegetation and heat storage

Urban surfaces absorb and release energy at night and vegetation is lower. In exams treat urban heat island as a multi factor effect.

Correct answer: A. When land areas heat strongly in Northern Hemisphere summer

Thermal equator shifts seasonally with the zone of maximum temperature. In exams do not treat it as a fixed geographic line.

Correct answer: C. Combined result of both factors will decide temperature

The direct answer is C: both factors together determine the temperature. Height and ocean or water currents can influence temperature at the same place, and their effects may oppose each other. With increasing altitude, air pressure generally falls and temperature usually decreases in the normal tropospheric pattern. A warm current can bring warmer water and warmer air toward a coastal area, raising temperatures or reducing the cooling effect. The final temperature depends on the combined influence and on the strength of each factor. Option A is wrong because altitude is not always the only control. Option B is wrong because the warm current is not the only control. Option C is correct because it allows both effects to operate together. Option D is wrong because temperature can be measured with instruments even when several factors affect it. Exam method: list every stated factor, note whether each warms or cools, and do not discard either one.

Correct answer: B. Cold dense air collected on valley floor

Cold air drains downward and pools on valley floor causing frost. In exams link valley frost with cold air drainage.

Correct answer: A. Shade and transpiration decrease and absorption increases

With forest removal and low albedo surface daytime heating can increase. Link land use change with temperature range in exams.

Correct answer: A. Clear night surface cooling cold lower air stable layer

In radiation inversion clear calm night cools surface and lower air. In exams understand the process in sequence.

Correct answer: A. More uniform temperature distribution due to ocean dominance

Southern Hemisphere has more oceans so temperature distribution stays relatively uniform. Link hemispheric difference with land water distribution in exams.

Correct answer: B. Dry inland desert

Very high daily range indicates dry inland conditions. In exams link large day night difference with desert dryness.

Correct answer: A. Daily temperature range will decrease

Clouds reduce heating by day and cooling by night. In exams treat clouds as reducing temperature range.

Correct answer: A. Inversion will weaken

Wind mixing combines cold and warm layers and reduces vertical contrast. Treat strong wind as inversion breaking in exams.

Correct answer: B. Different receipt of solar radiation

The direct answer is B, different receipt of solar radiation. When two mountain slopes have the same height, altitude cannot explain their temperature difference. The next important factor is aspect, meaning the direction in which a slope faces. A north-facing and a south-facing slope receive sunlight at different angles and for different effective durations, so they may heat differently. Option A, sea depth, is not the main reason for a difference between two slopes at the same mountain height. Option B is correct because unequal solar radiation produces unequal heating. Option C, earthquake intensity, concerns ground shaking and does not normally determine the regular temperature contrast between slopes. Option D, river flow, may affect a very local place but is not the general geographical explanation. In the Northern Hemisphere, south-facing slopes commonly receive stronger sunlight, although the exact result can depend on season, latitude, clouds and local conditions. Exam cue: same altitude plus different slope direction means compare solar radiation.

Correct answer: A. Vegetation shade and transpiration

Green areas can reduce heating locally. In exams treat land cover as important in microclimate.

Correct answer: B. Coastal temperature may be lower and daily range may increase

The direct answer is B: the coastal temperature may be relatively lower and the daily temperature range may increase. A cold ocean current cools the air near the coast and reduces surface heating. Dry air contains less water vapour; because water vapour helps moderate temperature, dry conditions can allow stronger daytime heating and greater night-time cooling. Thus the combined result can be a cooler coast with a larger daily range than a similarly placed humid coast. Option A is less correct because a cold current and dry wind do not produce fully maritime, humid conditions. Option B is correct because it includes both cooling by the current and increased range associated with dryness. Option C is wrong because temperature is controlled by several factors, including radiation, winds, currents, humidity, altitude and cloud cover, not rainfall alone. Option D is wrong because both the current and wind clearly influence temperature. The exact size of the effect depends on season and local geography, so “may” is important. Exam cue: cold current lowers temperature; dry air widens the daily range.

Correct answer: A. Zone of maximum temperature changes with solar position and land water distribution

Thermal equator shows the zone of maximum temperature which is not fixed. Treat it as seasonal thermal belt in exams.

Correct answer: A. Valley has temperature inversion and weak mixing

Direct answer: Option A, the valley likely has temperature inversion and weak mixing. Normally, air near the ground is warmed, rises, and mixes pollutants upward. During a temperature inversion, relatively warmer air lies above cooler surface air. The cooler dense air remains trapped near the ground, and the warmer layer acts like a lid. In a valley, surrounding relief can further restrict horizontal movement. Therefore industrial smoke can remain accumulated until morning while the air above stays comparatively clear. Option A matches both clues: valley location and persistent low-level pollution. Option B is wrong because strong convection would lift and dilute smoke rather than allow it to remain concentrated. Option C is wrong because an ocean current cannot directly trap smoke in an inland valley. Option D is wrong because strong, deep wind would disperse the smoke. Memory cue: cold air below, warm air above, pollution trapped below means inversion.

Correct answer: B. Dry area near low latitude

Low latitude may have small seasonal range but dryness can raise day night range. Keep annual and daily ranges separate in exams.
