Karst topography is a landscape or landform created when nearby groundwater or surface water dissolves rocks. Examples of karst topography include caves and sinkholes, as shown in the images. sinkhole near a home, a huge sinkhole in a habited region, and a man standing inside a cave

Based on your experimental results, what can you conclude about the type of rocks that once existed in these locations and the acidity of the nearby groundwater?

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.
