In the lab, I observed how convection moves Earth's
plates. I also saw how plates interact with each other.
When plates move apart from each other at divergent
boundaries, magma from the mantle reaches Earth's
surface and new crust forms. When plates move toward
each other at convergent boundaries, volcanoes,
mountains, and trenches form. When the plates rub
against each other at transform boundaries,
earthquakes may occur. Plate movements may change
the shape of Earth's surface and cause geologic events
such as earthquakes.
Which of these ideas did you include in your answer?
Check all that apply.

Convection currents move Earth's plates.

Plates interact with each other at plate boundaries,

The interaction of plates may cause the formation of features like volcanoes that change Earth's surface.

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.
