Is comparing your measurement to the actual or accepted value.

A group that is NOT experimented on is known as the Experimental Group.

Occurs when a material changes shape as a stress is applied and remains in the new when stress is removed.

Earth's surface is made of separate slabs of a rigid rock called what?

Occurs when a material deforms as stress is applied but snaps back into its original shape when stress is removed.

What type of data deals with descriptions (quality), such as, colors, appearance, texture, behavior, etc.

Step in scientific method: state the problem in the form of a question.

Name the three main branches of science:

Type of boundary when two continental plates of equal density collide and do not subduct creating folded mountains.

Are you ready for your EXAM?!!!

The boundary between two plates that are moving apart.

Meteorology is the sub-branch of Physical Science.

Proposed a hypothesis that suggested that Earth's continents were once part of a large supercontinent called Pangaea.

What is formed if an experiment is repeated many times and obtains the same results?

Boundary where plates slide horizontally past each other in opposite directions.

Sudden movement and vibration of the ground that occurs when rocks slip and slide among enormous cracks in Earth's crust

scientific method: form a hypothesis

scientific method: observe and record all results

scientific method: state conclusion about the problem based on the research and data collected

Name of scale that ranks earthquakes according to amount of damage they cause.

A crack in Earth's crust along which rock has moved is known as the epicenter.

Type of boundary when a thick, buoyant continental plate meets a thin, dense oceanic plate, dense plate dives beneath.

The form of measurement used by mosts scientist, also known as the metric system.

What is the metric measurement for volume?

What type of data deals with numbers (quantity)?
