Multiple choice biology living in harmony climate factors abiotic components organisms and environment

Low clouds retard surface cooling at night better than clear skies because:

  1. The clouds absorb and radiate infrared energy back to earth

  2. The water droplets in the clouds reflect infrared energy back to earth

  3. The clouds start convection currents between them

  4. The clouds are better conductors of heat than is the clear night air
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Clouds act as a blanket at night by absorbing longwave infrared radiation emitted by the Earth's surface and re-radiating a portion of it back down, which reduces the rate of surface cooling.

If a glass of water were surrounded by saturated air:

  1. The level of the water in the glass would slowly decrease

  2. The water's temperature would slowly increase

  3. The level of the water in the glass would not change

  4. The water's temperature would slowly decrease
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Saturated air contains the maximum amount of water vapor possible at a given temperature, meaning there is no net evaporation or condensation occurring at the water surface. Therefore, the water level remains constant because the rate of evaporation equals the rate of condensation.

The primary source of energy for the earth's atmosphere is:

  1. Energy from within the earth

  2. The sun

  3. Erupting volcanoes

  4. Lightning discharges associated with thunderstorms
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The sun provides the vast majority of the energy that drives atmospheric circulation, weather patterns, and the heating of the Earth's surface and atmosphere. Other sources like geothermal or volcanic activity are negligible in comparison to solar radiation.

If you want to keep an object cool while exposed to direct sunlight,

  1. Put it inside a brown paper bag

  2. Wrap it in black paper

  3. Wrap it in aluminum foil with the shiny side facing inward

  4. Wrap it in aluminum foil with the shiny side facing outward
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Aluminum foil is highly reflective. By placing the shiny side outward, it reflects the incoming solar radiation away from the object, preventing it from absorbing heat.

The lag in daily temperature refers to the time lag between the:

  1. Time of maximum solar radiation and the time of maximum temperature

  2. Time of minimum temperature and the time of maximum solar radiation

  3. Minimum and maximum temperature for a day

  4. Minimum and maximum solar energy received at the surface for a given day
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The lag in daily temperature occurs because the Earth's surface continues to receive and store heat even after the sun has passed its peak intensity at solar noon. The maximum temperature is typically reached a few hours after the maximum solar radiation.

What are sources of energy an ecosystem rely on?

  1. Wind energy

  2. Sunlight and Chemical energy

  3. Thermal Energy

  4. Wave energy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ecosystems are primarily driven by solar energy captured through photosynthesis. In some specialized environments, such as deep-sea hydrothermal vents, organisms rely on chemical energy (chemosynthesis) instead of sunlight.

In which ecosystem sun energy is replaced by highly concentrated potential energy of chemicals and fuels?

  1. Man subsidized solar power ecosystem

  2. Unsubsidized natural solar powered ecosystem

  3. Naturally subsidized solar powered ecosystem

  4. Fuel power ecosystem
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A fuel-powered ecosystem is one where the primary energy input is not solar radiation but rather the combustion of fossil fuels or other concentrated chemical energy sources, often seen in industrial or urban settings.

Water logged soils are generally 

  1. Physiologically dry

  2. Physiologically wet

  3. With great amount of water

  4. With less amount of water
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

If all the air spaces of soil are filled with water, the condition is known as water logging of soil. Such soils are physiologically dry soils. 

Therefore, the correct answer is option A

Multiple choice biology living in harmony climate factors abiotic components organisms and environment

Solar radiations heat up

  1. Land faster than the water bodies

  2. Land slower that the water bodies

  3. Equally both land and water bodies

  4. Neither land nor water bodies.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Solar radiation is radiant energy emitted by the sun. The land being darker and less reflective will absorb great deal of solar radiation and will have significant increase in temperature.

Multiple choice biology living in harmony climate factors abiotic components organisms and environment

Which one of the following is biotic in origin?

  1. Texture and porosity of soil

  2. Rainfall

  3. Carbon dioxide content of soil

  4. Light intensity
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Biotic factors are those related to living organisms. Carbon dioxide levels in soil are significantly influenced by the respiration of soil microbes, plant roots, and the decomposition of organic matter, making it biotic in origin.
