keywords: 

{'sound waves': [0, 0, 2, 9], 'pressure waves': [0, 0, 1, 0], 'wavelength': [0, 0, 3, 3], 'consecutive compression': [0, 0, 1, 0], 'distance': [0, 3, 3, 3]}

Option 1 states that the distance between two consecutive compressions is called the wavelength. This statement is correct. In a sound wave, there are areas of high pressure called compressions and areas of low pressure called rarefactions. The distance between two consecutive compressions or rarefactions is the wavelength. So, option 1 is correct.

Option 2 states that sound waves are pressure waves. This statement is also correct. Sound waves are mechanical waves that propagate through a medium, such as air or water, by causing the particles of the medium to vibrate. These vibrations create regions of high and low pressure, which travel as waves. Therefore, option 2 is also correct.

In summary, both option 1 and option 2 are correct statements about sound waves. So, the correct answer is option 3.
