Question

the rock cycle demonstrates that:
only igneous rocks can become sedimentary rocks
rocks can transform from one type to another
rocks remain unchanged over time
metamorphic rocks cannot be transformed

what symbol on a weather map represents a cold front?
red line with semicircles
blue line with semicircles
blue line with triangles
red line with triangles

which of the following is considered a renewable resource?
coal
geothermal energy
uranium
natural gas

Explanation:

First Question (The rock cycle demonstrates that: )

The rock cycle shows the processes by which rocks (igneous, sedimentary, metamorphic) can change into each other. Option 1 is wrong as any rock type can become sedimentary. Option 3 is wrong as rocks change over time. Option 4 is wrong as metamorphic rocks can transform. So the correct idea is rocks transform between types.

On weather maps, a cold front is represented by a blue line with triangles (the triangles point in the direction of movement). A warm front is red with semicircles. So the correct symbol for cold front is blue line with triangles.

Renewable resources are replenished naturally. Coal, uranium, and natural gas are non - renewable (fossil fuels or finite minerals). Geothermal energy is from Earth's heat, renewable.

Answer:

B. Rocks can transform from one type to another (assuming the second option is labeled B; if original labels were different, adjust, but based on the selection, the correct option is the one stating "Rocks can transform from one type to another")
