The question seems to be addressing the properties of acidic (or felsic) lava versus basic (or mafic) lava in terms of their viscosity.

Understanding the Concepts:

1. Acidic Lava: This type of lava is rich in silica and tends to be less fluid, meaning it has a higher viscosity. It tends to form steep-sided volcanoes and flows slowly.

2. Basic Lava: This lava has lower silica content, is more fluid, and therefore has a lower viscosity. This allows it to flow more easily over larger areas.

Filling in the Blank:

Considering the properties of each type of lava, the statement would be completed as follows:

"Acidic lava flows readily and tends to cover much larger areas, while basic lava is more viscous."

Summary:

In essence, while acidic lava is less viscous and covers large areas, basic lava is more viscous, making it less capable of spreading out widely. The correct completion of the phrase helps clarify the contrasting characteristics of different lava types and their flow behaviors.
