Question

1. which of these describes a renewable resource?

it takes a really long time to come back after we use it up.
it can be replenished in a relatively short period of time.
it is not affected by human use.
theres always an endless amount available.

Explanation:

Renewable resources are those that can be replenished or replaced relatively quickly through natural processes. For example, solar energy is constantly available as long as the sun shines, and forests can regrow if managed properly. The option "It takes a really long time to come back after we use it up" describes non - renewable resources like fossil fuels. The option "It is not affected by human use" is incorrect because human activities can impact the availability of renewable resources (e.g., over - farming can deplete soil fertility). The option "There's always an endless amount available" is also wrong as even renewable resources can be over - exploited.

Answer:

It can be replenished in a relatively short period of time.
