The process of weathering where rocks are broken down by changes in temperature, leading to expansion and contraction, is known as:
- Chemical Weathering
- Biological Weathering
- Mechanical Weathering (Thermal)
- Mass Wasting
Show answer
Answer: C. Mechanical Weathering (Thermal)
Thermal weathering is a form of mechanical weathering where repeated heating and cooling of rocks causes expansion and contraction, leading to stress and eventual breakdown. Chemical weathering involves chemical reactions, biological weathering by living organisms, and mass wasting is the downslope movement of rock and soil.
Deforestation contributes to which of the following environmental problems?
- Increased biodiversity
- Soil erosion and desertification
- Improved water quality
- Reduced atmospheric carbon dioxide levels
Show answer
Answer: B. Soil erosion and desertification
Trees play a crucial role in binding soil and maintaining soil structure. Their removal exposes the soil to weathering and erosion by wind and rain, which can lead to loss of fertile topsoil and the spread of desert-like conditions.
A landscape shaped by the dissolution of soluble rocks like limestone by water is known as a/an __________ landscape.
- Arid
- Glacial
- Karst
- Volcanic
Show answer
Answer: C. Karst
Karst landscapes are characterized by distinctive landforms such as sinkholes, caves, and underground drainage systems, formed by the chemical weathering and dissolution of soluble rocks, predominantly limestone.
Which of the following is a consequence of global warming?
- Decreased sea levels
- Melting of glaciers and ice sheets, leading to rising sea levels
- More stable weather patterns
- Expansion of polar ice caps
Show answer
Answer: B. Melting of glaciers and ice sheets, leading to rising sea levels
Global warming, driven by increased greenhouse gas concentrations, causes higher global temperatures. This leads to the melting of ice masses, contributing to a significant rise in sea levels, which poses risks to coastal communities and ecosystems.
Which type of cloud is typically associated with fair weather?
- Cumulonimbus
- Stratus
- Cirrus
- Cumulus
Show answer
Answer: D. Cumulus
Cumulus clouds are the puffy, white clouds often seen on sunny days. While they can develop into cumulonimbus clouds that produce thunderstorms, the smaller, fair-weather cumulus indicate stable atmospheric conditions.
