He said the intent is to stop the cycle of revenge and violence.

Water is thus extremely mobile and moves rapidly over the planet in a continuous hydrologic cycle.

So it's sort of a cycle through which the cracks and the wedges grow wider and wider.

These butterflies require the presence of ants to complete their life cycle.

Do you recall? Cathy. How this S-curve represents the life cycle of innovation?

Two factors appear to be generating the cycle: food plants and predators.

By far the most abundant type of groundwater is meteoric water; this is the groundwater that circulates as part of the water cycle.

The gradual drying of the soil caused by its diminished ability to absorb water results in the further loss of vegetation, so that a cycle of progressive surface deterioration is established.

It happens in cycles.

These change, often in cycles, increasing and decreasing slowly over time.

Well, geomagnetic activity, the natural variations in Earth’s magnetic field, it fluctuates in 11-year cycles.

Heated by the Sun, the water moves in great cycles from the oceans to the atmosphere, over the landscape in river systems, and ultimately back to the oceans.

These change, often in cycles, increasing and decreasing slowly over time.

It happens in cycles.

The areas that are now desert were, like all arid regions, very susceptible to cycles of higher and lower levels of rainfall, resulting in major, sudden changes in distributions of plants and animals.

Population cycles are characteristic of small mammals, and they sometimes appear to be brought about by predators.

However, these same cycles of change had momentous impacts on the sparse human populations of the region.

From this analysis of marine sediments, geologists have learned that there were many shorter, more regular cycles of glaciation and deglaciation than geologists had recognized from the glacial drift of the continents alone.

From this information, he was able to confirm the existence of a pattern, a repeating cycle but Wolf detected an 11-year cycles?

11-year cycles?

Well, geomagnetic activity, the natural variations in Earth’s magnetic field, it fluctuates in 11-year cycles.

Well, we’ll cover this later in this semester, but for now, well, scientists in the late 19th century were aware of geomagnetic cycles, so when they heard that the sunspots’ cycle was also 11 years, well, they just had to find out what was going on.

Like almost all daily cycles of animals deprived of environmental cues, those measured for the horseshoe crabs in these conditions were not exactly 24 hours.

Further evidence for persistent internal rhythms appears when the usual external cycles are shifted—either experimentally or by rapid east-west travel over great distances.

Normally, internal rhythms are kept in step by regular environmental cycles.

Now you should know that this job candidate is interested in the life cycles in the forest.

The three most important nutrient cycles are the nitrogen cycle, the carbon cycle and the one we are going to talk about today, the Phosphorus cycle.

See, zinc plays a major role in carbon cycling, the conversion of various kinds of molecules with carbon, Iike carbon dioxide, into other kinds of molecules with carbon that organisms can use．

Unlike rain, which returns rapidly to the sea or atmosphere, the snow that becomes part of a glacier is involved in a much more slowly cycling system.

He cycled to Ingwold.

First it was yoga, then rock climbing, cycling.

The machine has 10 cycles per second.

We went for a cycle ride on Sunday.
