What zone is alternately dry and submerged?

In an ocean, the intertidal zone is alternately submerged and dry during high and low tides, respectively; the neritic zone is near shore, extending from the intertidal zone to the edge of the continental shelf; and the oceanic zone is farthest from shore and therefore does not receive much of the nutrient load from …

Which aspects of a region’s climate have the most impact on plants and animals?

Temperature and moisture are the aspects of a region’s climate that have the most impact on plants and animals. You just studied 25 terms!

At what time of year is the intensity of solar radiation striking each of Earth’s hemispheres weakest?

The Northern Hemisphere is tilted toward the sun. At what time of year is the intensity of solar radiation striking each of Earth’s hemispheres weakest? The intensity of solar radiation is weakest in the Southern Hemisphere in June and in the Northern Hemisphere in December.

What part of Earth gets the most direct sunlight?

the equator

How is light energy carried from the Sun to Earth?

How does the sun’s energy travel to earth? The radiant energy is carried by packets of light called photons. The photons are bundles whose energy depends on frequency. The radiant energy corresponds to a range of wavelengths on the electromagnetic spectrum, of which visible light is only a small portion.

Can we stop a photon?

No, it is not possible to stop a photon. Photons are always moving. They have a constant total energy and kinetic energy of ( p c ). The rest mass of photons is always zero which means they have zero rest energy.

What happens to a photon when it stops?

If we try to stop the photon then the photon will disappear and its energy will be transferred to some other material or object.

Can a photon be still?

1 Answer. No, we cannot make photons travel at any value other than the speed of light. It is a postulate of the theory of relativity and it works because solutions to the equations of electromagnetism indicate that light/photons must travel at a constant speed regardless of observer.

Can the time be stopped?

The simple answer is, “Yes, it is possible to stop time. All you need to do is travel at light speed.” Special Relativity pertains specifically to light. The fundamental tenet is that light speed is constant in all inertial reference frames, hence the denotation of “c” in reference to light.

How does light behave in space?

Light behaves both as a particle and as a wave. Depending on the situation, it can be easier to talk about photons the light particle, or light waves- for travelling the vast distances of space, either works. However, light’s energy is very tightly tied to one of its more wave-like properties – its wavelength.

Does light travel forever?

Light is made up of particles called photons that travel like waves. Unless they interact with other particles (objects), there is nothing to stop them. If it is infinite, the light would travel forever.

At what temperature do lakes turnover?

In other words, when water reaches the critical temperature of 39 degrees Fahrenheit, further cooling causes the water molecules to become less dense and rise to the surface. This unusual characteristic allows water to form distinct layers within an otherwise uniform liquid.

At what temperature is water most dense?


Why is water most dense at 39 degrees?

At 39°F (or 3.98°C to be exact) water is the most dense. This is because the molecular structure and hydrogen bonding of the water takes up more space when it is a frozen solid rather than when it is a warmer liquid. In other words, the molecules are farther part even though the water is solidifying into ice.

Is it possible to change the density of water?

The density of water can also be affected by temperature. When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume.

Why salt water makes you float?

Low density makes it more difficult for objects and people to float. Salt increases water’s density by changing its mass without significantly changing its volume. With enough salt in the water, a person will become buoyant and float.
