scientific method: form a hypothesis

Is comparing your measurement to the actual or accepted value.

Which variable is changed during an experiment?

The continuous heating and cooling process that produces convection currents in the mantle that move plates.

What is the metric measurement for length?

What types of fossils were ideal to observe according to Alfred Wegener's hypothesis of the Continental Drift?

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

Meteorology is the sub-branch of Physical Science.

Write 28750.9 in scientific notation.

What variable is measured during the experiment, does not change?

The age of seafloor crust increases with distance from the ridge.

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

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

scientific method: write down the procedures you will use to test your experiment

The boundary between two plates that are moving apart.

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

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

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

Scientific method: research the problem

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

The point of origin for an earthquake is called the epicenter.

Write 531.42 x 10⁵ in Scientific Notation.

The points on Earth's surface directly above the focus is called the epicenter

Is a description of how close measurements are to each other.

Express 4.58 x 10⁶

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

A long, narrow depression on the seafloor.

What type of data deals with numbers (quantity)?

What are mountain ranges on the seafloor separated by sea valleys called?

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

scientific method: interpret data

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

What is the metric measurement for mass?

Express 1.8 x 10^-4 in Decimal (regular) notation.

Turn question in a hypothesis statement: Does water help a plant grow?

What is the easier way or method of writing a very large number called?

Something that has been proven to be true and correct numerous times, and can explain why something happens

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

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

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

scientific method: perform experiment to test hypothesis

The human effort to understand the natural world, how it works, and discover knowledge is known as?

Name the three main branches of science:

Are you ready for your EXAM?!!!

What is the metric measurement for volume?

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

Waves that travel outward in all directions from the point where the staring energy is released.

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

The three major seismic waves are:

scientific method: observe and record all results

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

What is the formula for calculating seafloor spreading distances?

A logarithmic scale that measures the amplitude of the largest seismic wave recorded on a seismograph.

Who revived Wegener's hypothesis about the continents drifting and used sonar to develop 3-D maps of the seafloor?
