Metric and English Units Quiz

The amount of matter in an object. It is measured in kilograms (kg), grams (g), and milligrams (mg).

The speed at which an object can travel the fastest. It is measured in kilometers per hour (km/hr).

The relationship between two things, where one thing changes as the other changes. This can be shown on a graph, plotting data points.

A graph used to visualize the relationship between two sets of data, where one set of data is plotted on the horizontal (x) axis, and the other set of data is plotted on the vertical (y) axis.

A scientific investigation that aims to test a relationship between two variables by systematically changing one variable and observing the effects on the other variable. This typically involves collecting data, analyzing the data, and drawing conclusions.

An educated guess about the relationship between variables, used to predict an experiment's outcome.

Factors that can be changed or controlled in an experiment. They influence the outcome.

Factors that are kept constant in an experiment. They don't change, ensuring a fair comparison.

The process of collecting data and making observations to gather information about variables and their relationships.

A summary of the findings and a statement of whether the hypothesis was supported or rejected based on the collected data.

The factor that is changed in an experiment. It's the cause that you manipulate to see its effect.

The factor that is measured in an experiment. It's the effect or outcome you're observing.

The factors that are kept constant throughout an experiment. This ensures that only the independent variable is affecting the dependent variable.

A question that asks about the relationship between two variables, often investigating whether one affects the other.

A question that cannot be answered by observation, experiment, or measurement.

The theory that continents were once joined together and have drifted apart over time, based on similarities in coastlines and matching fossils.

A German meteorologist who proposed the theory of continental drift based on evidence like matching fossils on different continents and the shapes of coastlines.

Evidence supporting the idea of continental drift, such as fossils of identical species found on continents now separated by oceans.

The idea that the Earth's continents have moved significantly over geological time. Previously thought impossible, it is now a well-accepted scientific theory.

Similar shapes of coastlines, such as the coast of Africa and South America, which suggest a potential past connection.

The process of breaking down rocks, soil, and minerals through physical or chemical means.

The movement and transportation of weathered material from one location to another.

A type of weathering caused by physical forces, such as the expansion and contraction of rocks due to temperature changes or the action of moving water.

A type of weathering caused by chemical reactions, such as rusting or the breakdown of rocks by acidic water.

Depressions or holes in roads caused by the expansion and contraction of pavement due to temperature changes and the action of water freezing and expanding in cracks.

A vast underwater mountain range that winds around the globe, where new oceanic crust is formed.

The process where new oceanic crust is formed at the Mid-Oceanic Ridge and then pushed away as more crust forms.

Rocks farthest from the Mid-Oceanic Ridge are older than rocks closer to it, indicating that the ocean floor is constantly expanding.

The Earth's crust is comprised of large and smaller plates that move slowly over the mantle.

The Mid-Oceanic Ridge is an example of a divergent plate boundary, where two plates move apart, allowing new crust to form.

The uppermost layer of soil, rich in decomposed organic matter (humus).

The topsoil layer, containing a mix of mineral and organic matter, vital for plant growth.

The subsoil layer, primarily composed of minerals and less organic matter.

A layer of broken-down rock, sometimes called 'parent material,' that forms the base for soil development.

The solid bedrock that lies beneath all other soil layers.

The theory that continents were once joined together in a supercontinent called Pangaea and have since drifted apart due to movement of the Earth's crust.

Heat within the Earth's mantle creates currents, moving plates above them.

Deep, narrow depressions in the ocean floor, often near the edges of continents, where one plate slides underneath another.

Elevated regions in the ocean floor, often in the middle of oceans, where magma rises from the Earth's mantle.

The process of the Earth's crust moving and changing over time, driven by convection currents in the mantle.

Two tectonic plates moving towards each other, resulting in the formation of mountains if both are continental, or subduction of denser oceanic crust under continental crust if one is oceanic.

Two tectonic plates pulling apart, allowing magma to rise and create new oceanic crust.

Two tectonic plates sliding past each other, causing friction that builds up and releases as earthquakes.

The process of an organism becoming a fossil, involving rapid burial, soaking in groundwater, mineral replacement, and hardening.

The topmost layer of soil, containing decomposed organic matter, roots, and small organisms.
