____ has been a lot of discussion on why moths are attracted to light.

The consensus seems to hold that moths are not so much attracted ____ lights as they are trapped by them.

The light becomes a sensory overload that disorients the insects ____ sends them into a holding pattern.

A hypothesis called the Mach band theory suggests that moths see a dark area around a light source and ____ for it to escape the light.

Another theory suggests that moths perceive the light coming from a source as ____ diffuse halo with a dark spot in the center.

The moths, attempting to escape the light, fly toward ____ imagined “portal,” bringing them closer to the source.

As they approach the light, their ____ point changes and they circle the light hopelessly trying to reach the portal.

Everyone is familiar ____ moths circling their porch lights.

Their flight appears to have no purpose, but they are, it is believed, trying to ____ the pull of the light.

There is ____ problem from biology called “the paradox of enrichment.”

Intuitively, ____ would think that a population of predators would tend to do better if the amount of food available to its prey were to increase.

More food for the prey means that more prey is ____ to the predator, and hence the predators’ population should expand as well.

Yet, in fact, ____ the opposite happens.

An increase in the food available to rabbits, for example, in a given area might lead to an overabundance of rabbits, and increase the population of its predator — say, wolves ____ until the population of wolves becomes unsustainably large and is destabilized.

So, more food for the rabbits can actually pose a threat to the ____ of wolves.

This example shows that our ordinary intuition — that more food and ____ more prey is always good for a predatory group — is flawed.

More is not always more, at least in the case ____ predators and prey.

The ____ of enrichment shows that our intuitions about abundance and enrichment do not always conform to observable facts.

Our planet is about ____ billion years old.

Much of the Sahara ____ underlain by rocks that date back to between 2.5 billion and 500 million years ago.

These rocks have been greatly altered by extreme heat and pressure and have long been known by the very general term Basement ____

The Basement Complex rocks have undergone periodic intervals of uplift and deformation followed by intervals ____ prolonged erosion.

They are overlain by more or less ____ sedimentary rocks that were laid down by water, wind, and ice.

This sedimentary cover is up to ten kilometres thick and ____ well over half of the present Sahara.

As a result, ____ Complex rocks are only visible at the surface of the Sahara in about 15 percent of its total area.

The contact between Basement Complex and sedimentary cover is often ____ sharp and is sometimes evident as a line of springs, some still active, some long dry.

The drive toward equilibrium, a minimum energy state where there is no further tendency to change, is one of the ____ principles of chemistry and physics.

Falling objects come to rest at the lowest energy state; chemical reactions ____ to completion where no further reaction occurs.

While this driving force is manifest everywhere, natural systems, even when they ____ at a steady state, are usually far from equilibrium.

At ____ properties such as temperature and pressure are constant throughout the system, and the system is isolated from external influences.

That is not the natural world! One of the benefits of laboratory experiences is that when we actually try to measure properties at equilibrium, it becomes evident that controlling the conditions for such ____ to appear is very difficult indeed.

____ systems are not isolated.

Matter flows in and out; properties ____ as temperature and pressure change continuously.

Natural phenomena do not exist in static equilibrium states, but are in movement at all ____
