A geographer states, 'The desert felt much hotter than the forest.' An atmospheric scientist follows up by saying, 'The solar intensity in the desert was 1,250 W/m², while in the forest it was 700 W/m².' What is the key advantage of the scientist's statement?

It uses more complicated language.

It provides specific, measurable data.

It describes the color of the landscape.

A scientist studying the effects of sunlight on skin health wants to collect quantitative data. Which of the following represents a quantitative measurement?

Noting that the sunlight feels very warm on the skin.

Observing that the sky is clear and blue.

Recording the solar intensity as 1,100 watts per square meter.

Describing the location as a sunny tropical beach.

Because 'sunny' is a scientific term with a precise definition.

Because it allows for a precise, objective comparison of the amount of energy different locations receive.

Because solar intensity can only be measured on cloudy days.

Because the term 'sunny' is only used to describe weather in the Southern Hemisphere.

Sydney is a better place to live than Anchorage.

Anchorage receives less solar energy per unit of area than Sydney.

It is always cloudy in Anchorage.

The Earth is tilted away from the sun in Sydney.
