1st Semester Science Review

Front

What is a rock fall?

Back

A rock fall is a type of mass wasting where rocks fall freely from a steep slope or cliff due to gravity.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of molten rock (magma or lava).

Front

What is the correct order of Earth's layers from the center to the surface?

Back

Inner core, Outer core, Mantle, Crust.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often causing one plate to be forced below the other.

Front

How can cities reduce smog levels?

Back

Cities can reduce smog levels by decreasing the number of individual cars and increasing the number of buses.

Front

What is a mudflow?

Back

A mudflow is a rapid flow of mud down a slope, often triggered by heavy rainfall or volcanic activity.

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid and composed mainly of iron and nickel, while the outer core is liquid and also made of iron and nickel.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often creating new crust as magma rises to the surface.

Front

What is smog?

Back

Smog is a type of air pollution that is a mixture of smoke and fog, often caused by vehicle emissions and industrial discharges.

Front

What is creep in geology?

Back

Creep is the slow, gradual movement of soil and rock down a slope due to gravity.
