Venus and Earth are sometimes referred to as "sister planets" because they share some similarities. The two planets are about the same size and have about the same mass, or weight. However, these two planets have many differences. Venus has no oceans and is much
hotter than Earth. Venus alsorotates, or spins, in a clockwise direction. All of the other planets rotate in a counter-clockwise direction.
For each feature in the left column, select a box on the right to show whether it shows how Venus and Earth are similar or how the two

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
