Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

US temperatures have increased by approximately 1.2°F (0.7°C) over the last century, which is less than 1°C. This is consistent with global warming patterns observed worldwide.

Multiple choice

  2. Only b

  3. Only c

  5. None of the above
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This is the correct answer choice, as all the statements are correct.

Multiple choice

The idea that the major portion of Earth would be submerged followed by a prolonged ice age as a result of global warming is implausible. Weather forecasters cannot dependably predict the next day’s weather. Yet the effects of the global warming on our planet’s structure and climate would follow the same physical laws that govern normal changes in the weather being predicted. If scientists cannot predict the day-to-day weather using our current knowledge, they certainly cannot predict the effects of global warming on Earth’s climate.

Which of the following statements would most seriously weaken the author’s conclusion?

  1. The theory predicting the effects on Earth being submerged by water causing return of ice age is based on studies that are readily available to weather forecasters.

  2. The effects of Earth being submerged will create drastic atmospheric changes rather than the type of day-to-day weather changes seen.

  3. Weather forecasters do not require predictions to be 100 percent accurate.

  4. Attempts to predict the effects of natural catastrophes such as global warming have been found to be less reliable than normal weather predictions.

  5. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This answer shows that the inability to predict daily weather changes doesn’t indicate an inability to predict weather changes that would result from submergence of Earth as a result of global warming.

Multiple choice

Which of the following factors does not affect the temperature of a particular region?

  1. Pollution

  2. Number of trees

  3. Density of population

  4. Nature of soil
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soil nature (texture, composition) does not directly affect air temperature. Pollution can affect temperature through the greenhouse effect and urban heat islands. Trees affect temperature through shade and evapotranspiration. Population density creates urban heat islands. Soil is not a climatic factor.

Multiple choice

Which of the following factors does not affect the climate of the earth?

  1. Distance from sun

  2. Earth's shape

  3. Earth's tilt

  4. Distance from equator
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Earth's shape (being an oblate spheroid) is not a factor that affects climate. Climate is influenced by distance from the sun (solar radiation), Earth's tilt (causes seasons), and distance from the equator (latitude affecting solar angle and temperature distribution). The spherical shape itself doesn't vary between regions.

Multiple choice

Which of the following correctly defines climate?

  1. A change in the atmospheric condition

  2. Weather of a place over a long period of time

  3. General conditions of atmosphere at a particular time and place

  4. Temperature at a particular region
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Climate refers to the average weather conditions (temperature, humidity, precipitation, wind) observed over a long period, typically 30+ years. Unlike weather (short-term atmospheric state), climate represents long-term patterns and trends.

Multiple choice

Greenhouse effect causes __________.

  1. increase in global temperature

  2. increase in rains

  3. decrease in global temperature

  4. increase in crop production

  5. deforestation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Greenhouse effect causes increase in global temperature.

Multiple choice

How does latitude affect the temperature of a place?

  1. The higher the area, the cooler the place.

  2. The curvature of the earth affects temperature.

  3. The Coriolis force is affected by the latitude.

  4. The latitudes affect the cyclonic disturbances.

  5. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is the correct answer as due to the curvature of the earth, the amount of solar energy received varies according to latitude. As a result, air temperature generally decreases from the equator towards the poles.

Multiple choice

Directions: Choose the option that is not an effect of the given cause. Cause: The day time temperature in summer has been four to five degree Celsius above the normal temperature across the country. Which of the following cannot be a possible effect of the above cause?

  1. All the district headquarters are alerted.

  2. Many people are confined to their home.

  3. Govt. has ordered that all the offices and schools be kept closed.

  4. This has resulted in a significant climatic change.

  5. All of these can be the effects.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

We are talking about temperature increase not of climate change.

Multiple choice

Global warming has resulted due to

  1. increased level of oxides of sulphur and nitrogen

  2. increased emissions of CO2 from automobiles

  3. increased flatulence of animals

  4. increased emissions of fine particulates from automobiles
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Global warming has resulted due to increased emissions of CO2 from automobiles. The main cause of it is greenhouse effect. Naturally occurring amounts of greenhouse gases have a mean warming effect of about 33 °C (59 °F). The major greenhouse gas is carbon dioxide (CO2) which causes 9-26% of greenhouse effect.

Multiple choice

Polar ice caps are expected to be very severely affected by global warming. Which of the following will be its immediate effect?

  1. Reduced hunting ranges for polar bears

  2. Increased risk of icebergs

  3. Increased opportunity for exploration in the Arctic

  4. Coastal and island flooding

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Polar ice caps are expected to be very severely affected by global warming. The immediate effect of it could be coastal and island flooding. The main consequence of global warming is the loss of coastal wetlands and barrier islands, and a greater risk of flooding in coastal communities. Low-lying areas, such as the coastal region along the Gulf of Mexico and estuaries like the Chesapeake Bay, are especially vulnerable. 

Multiple choice

Which of the following factors does not affect the climate of the earth?

  1. Distance from sun

  2. Earth's shape

  3. Earth's tilt

  4. Distance from equator
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Earth's shape (being spherical/oblate spheroid) does not significantly affect climate - it's relatively constant. The factors that DO affect climate include: distance from the sun (affects solar radiation received), Earth's tilt (23.5° - causes seasons), and distance from equator (latitude - determines temperature zones). Earth's shape itself is not a variable climate factor.
