Which characteristics would one expect to find when studying the cooled lava?

volcanic, or extrusive, igneous rocks formed at Earth’s

surface. Some intrusive rocks, known as subvolcanic, were not

formed at great depth but were instead injected near the surface

where lower temperatures result in a more rapid cooling

process; these tend to be aphanitic and are referred to as

hypabyssal intrusive rocks

hygrometers and hair thermometers (often found as part of hygrometers/psychrometers) can be used to measure humidity. barometers are used to measure atmospheric pressure, while anemometers are used to measure wind speed. so the 2nd and 4th choices should be the correct answers.
