How old is someone right now that was born on leap year 8 years ago?

If he was born 8 years ago, then he is 8 years old now.

If he was born on February 29th, then most years
won't have the date of his birth in them.  Too bad.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
