What is the process that transforms sedimentary rock into igneous rock?

Back

Sedimentary rock can be transformed into igneous rock through melting and cooling, typically occurring when tectonic plates push sedimentary rock under Earth's surface, causing it to melt into magma.

Front

What distinguishes bacteria from viruses?

Back

Bacteria are living organisms that can reproduce on their own, while viruses are nonliving and require a host cell to replicate.

Front

What type of plate movement leads to the formation of a volcano at a subduction zone?

Back

A volcano forms at a subduction zone when an oceanic plate collides with a continental plate, causing the oceanic plate to be forced down into the mantle.

Front

How do the inner core and mantle of the Earth compare in terms of density?

Back

The inner core is denser than the mantle.

Front

What role do the respiratory and circulatory systems play in maintaining homeostasis during exercise?

Back

During exercise, the respiratory system increases breathing rate to obtain more oxygen, while the circulatory system increases blood flow to deliver oxygen and nutrients to cells.

Front

What is the definition of tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological events such as earthquakes and volcanic eruptions.

Front

What is magma?

Back

Magma is molten rock located beneath the Earth's surface, which can cool and solidify to form igneous rock.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breakdown of rocks into smaller particles, while erosion is the movement of those particles from one location to another.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What is the significance of the rock cycle?

Back

The rock cycle describes the continuous process of rock formation, breakdown, and reformation, illustrating how different types of rocks are interconnected.
