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

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

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

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

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

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

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

____ is familiar with moths circling their porch lights.

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

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

Intuitively, one would think that a population of ____ 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 available to the predator, and hence the predators’ population ____ expand as well.

____, in fact, sometimes 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 ____ 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 ____ to the population of wolves.

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

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

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

Our planet is about 4.6 billion ____ old.

Much of the Sahara is ____ 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 ____ and have long been known by the very general term Basement Complex.

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

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

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

As a result, Basement Complex ____ 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 very sharp and is sometimes evident as a line of springs, some still active, some long ____.

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

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

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

At equilibrium, properties such as temperature and ____ 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 perfection to ____ is very difficult indeed.

Natural ____ are not isolated.

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

Natural phenomena do ____ exist in static equilibrium states, but are in movement at all scales.
