b) Extraction of tar sands involves surface mining
c) Tar sands have a lower environmental impact than conventional oil
d) Processing tar sands requires significant water and energy

Answer 1

The incorrect statement about tar sands is that they have a lower environmental impact than conventional oil, which is not true due to their significant environmental footprint through surface mining and high resource usage.

Step-by-step explanation:

The subject of this question is the environmental impact and extraction process of tar sands (oil sands), which are a type of unconventional oil resource. Among the statements given, the one that is not correct is: c) Tar sands have a lower environmental impact than conventional oil.This statement is false as the extraction and processing of tar sands often lead to severe environmental consequences, including significant landscape disturbance due to surface mining, substantial water and energy use, and higher greenhouse gas emissions compared to conventional oil resources.
