Question 1

What is the name of ice accumulation at the foot of mountain ranges where several valley glaciers emerge, flow laterally, and coalesce?

Accepted Answer

Piedmont glaciers form when steep valley glaciers spill into relatively flat plains, where they spread out into bulbous, broad sheets. This occurs at the base of mountain ranges where several valley glaciers merge.

Question 2

Which of the following apply to Greenland and Antarctica?

Accepted Answer

Greenland and Antarctica are covered by continental ice sheets, which are massive ice masses that cover large areas of a continent.

Question 3

What is ablation?

Accepted Answer

Ablation refers to the process of melting or wasting away of glacial ice, often due to the effects of sunlight, warm temperatures, or wind.

Question 4

Increasing temperatures of earth's surface and lower atmosphere provide strong evidence that global warming is happening right now. This evidence includes all of the following except:

Accepted Answer

The greatest amount of warming due to global warming has been observed at higher latitudes and during the night, not during the day near the equator. This is because global warming leads to more uniform temperatures across the planet, reducing the temperature difference between day and night and between the equator and the poles.

Question 5

What is the name given to a coastal glacial valley that has been drowned by the sea?

Accepted Answer

Fjords are deep, narrow, and elongated sea or lake drains, with steep land on three sides, formed by the submergence of a glaciated valley.

Question 6

What is glacial outwash?

Accepted Answer

Glacial outwash refers to sediment deposited by meltwater streams flowing from a glacier.

Question 7

According to the Oregon energy office, which of the following actions will bring about the greatest reduction in CO₂ in pounds per year?

Accepted Answer

Buying a fuel-efficient automobile with a rating of at least 32 mpg to replace your most-used car brings about the greatest reduction in CO2 emissions per year, as transportation typically accounts for a significant portion of an individual's carbon footprint, especially in places with high reliance on personal vehicles.

Question 8

According to the United Nations what estimated percentage of all energy-related CO₂ emissions will developing countries be responsible for by the year 2025?

Accepted Answer

The answer of According to the United Nations what estimated...

Question 9

According to the Intergovernmental Panel on Climate Control (IPCC), what is expected to decrease in the 21^st century?

Accepted Answer

Biodiversity is expected to decrease in the 21st century due to factors like habitat destruction, climate change, pollution, and overexploitation of resources, as highlighted by the IPCC.

Question 10

Judge the following sentence according to the criteria given below: The worldwide retreat in mountain glaciers is significant BECAUSE these glaciers' reaction times are much slower than the ice sheets of Antarctica and Greenland.

Accepted Answer

The worldwide retreat in mountain glaciers is significant due to their contribution to sea-level rise and freshwater resources, but their slower reaction times compared to ice sheets is not the reason for their significance.

Question 11

Which of the following statements about the Greenland and Antarctic ice sheets is false?

Accepted Answer

The answer of Which of the following statements about the...

Question 12

Judge the following sentence according to the criteria given below: The decline of glacial ice in alpine and ice-cap glaciers from mid- and low-latitudes is not significant BECAUSE only very few glaciers have been surveyed.

Accepted Answer

The decline of glacial ice in alpine and ice-cap glaciers, especially from mid- and low-latitudes, is significant and has been well-documented through numerous studies, not just a few surveys. This indicates that both the assertion and the reason provided are incorrect.

Question 13

Which of the following has lost the greatest percentage of its ice mass over the past few decades?

Accepted Answer

Mount Kenya, Africa, has experienced a significant loss in ice mass, with its glaciers retreating at an alarming rate over the past few decades. This is attributed to global warming and climate change, which have had a profound impact on ice masses in equatorial mountain regions.

Question 14

The greatest amount of the increased temperature that Earth experienced during the 20^th century occurred at:

Accepted Answer

The greatest increase in temperature during the 20th century occurred at nighttime in higher latitudes. This is due to a phenomenon known as polar amplification, where changes in the Earth's climate lead to greater temperature increases near the poles compared to the global average. Additionally, nighttime warming is often more pronounced than daytime warming due to factors like decreased cloud cover and changes in atmospheric composition affecting heat retention.

Question 15

What percent of the world's energy comes from burning fossil fuels?

Accepted Answer

Fossil fuels account for more than 80% of the world's energy supply.

Question 16

The blizzards and subzero, bone-chilling cold over Eastern Europe and Russia in February 2012 have been attributed to

Accepted Answer

A negative Arctic Oscillation is a weather phenomenon that involves a weakening of the usual pressure patterns in the Arctic region. This can lead to colder air being pushed southwards into mid-latitudes, including Eastern Europe and Russia, which can result in the severe winter conditions described.

Question 17

Which of the following statements about coal as an energy source is false?

Accepted Answer

Coal is not sparse; it is actually one of the most abundant fossil fuels on Earth. This abundance contributes to its widespread use for energy production.

Question 18

Which of the following geoengineering techniques involves capturing greenhouse gases from smokestacks and pumping it underground?

Accepted Answer

Carbon capture and sequestration (CCS) is the process of capturing carbon dioxide (CO2) emissions from sources like power plants and industrial facilities and then transporting it to a storage site where it is injected into underground geological formations for long-term storage, preventing it from entering the atmosphere.

Question 19

Which of the following geoengineering techniques involves using 17 million 50-foot high resin-based carbon dioxide scrubbers?

Accepted Answer

The technique described involves using resin-based scrubbers to capture carbon dioxide directly from the atmosphere, which aligns with atmospheric capture of CO2.

Question 20

Which of the following geoengineering techniques involves injecting large amounts of sulfur dioxide aerosols into the stratosphere?

Accepted Answer

Solar radiation management (SRM) involves techniques aimed at reflecting sunlight to reduce global warming. Injecting sulfur dioxide aerosols into the stratosphere is a proposed SRM method to mimic the cooling effects of volcanic eruptions, which naturally release large amounts of sulfur dioxide into the stratosphere, leading to temporary cooling.
