Imagery

The type of imagery from your example ("there was fresh sand between the driveway paving stones and a diminutive sapling on the lawn") would be visual. You're attempting to paint a picture in the reader's mind to describe the house as being new.

You can use imagery to appeal to any of your reader's senses. Attempting to describe a particular smell would be one...

The acrid stench of burnt hair lingered in the air.

EDIT: Wikipedia has a decent description of sensory imagery.

The terms are "Cardinal" and "Ordinal" and "Distributive". One, two, three, etc. are "Cardinal Numbers." First, second, third, etc. are "Ordinal Numbers" (which tell Order). "Distributive Numbers" tell how many of each like Singly,Doubly,Triply and Single,Double,Triple.

We often get the various -nary terms like binary, ternary, and quaternary from Latin distributive numbers (bini, terni, quaterni, quini, seni, etc.), with the exception of unary which comes from their cardinal number one (unus) as opposed to their distributive number one (singuli, which is where singular, single, singularity, etc. come from). Words like primary, secondary, and tertiary usually come from their ordinal numbers (primus, secundus, tertius, quartus, quintus, etc.).
