What property of water allows water spider to walk across the surface of a pond?
In physics, surface tension is a force present within the surface layer of a liquid that causes the layer to behave as an elastic sheet. It is the force that supports insects that walk on water, for example.
Which mineral property is identified by the color of the powder left behind when it is rubbed across a surface?
The mineral property identified by the color of the powder left behind when a mineral is rubbed across a surface is called the mineral's streak.
An insect is able to walk across the surface of a pond without sinking because of the?
Insects are able to walk across bodies of water without sinking because of their weight. Insects weigh literally nothing.
What are the insects that use their skin to walk across thd surface of the stream?
Insects that are able to walk across the surface of water are called water striders. Water striders make use of the high surface tension of water together with their long, hydrophobic legs to stay above water.
Why is an insect able to walk across the surface of a pond without sinking?
Insects that have the ability to walk on water have feet that are spread very far apart. This allows their weight to be distributed over a larger area and stops them from breaking the surface tension of water molecules sticking together.
Why is surface tension helpful to some oragisms?
Many insects and microscopic organisms need to be in direct contact with the air to feed, live, and reproduce. The surface tension on water allows many insects to "walk" across the surface making the capture of prey much easier. During the hatching cycle, many insects larvae come to the surface of the water, using the surface tension for support while releasing the larvae inside.
What happen to the needle when you added 2-3 drops of the detergent solution?
The needle floats on the tensioned surface of the water. When the detergent is added, the surface tension is broken and the needle sinks. Larva of mosquitoes hang from the surface to breath air. Pond-skaters can move across the surface, as can many aquatic insects. Detergent will also cause insects to sink.
What is an example of a sentence using the word skitter?
It amuses me to see the insects skitter across the surface of the pond.
How can you explain surface tension?
Surface tension is a property of liquids that arises from the cohesive forces between the molecules at the surface. It is responsible for the "skin-like" effect that allows some insects to walk on water. Surface tension minimizes the surface area of liquids to maintain their integrity and is measured in units of force per unit length.
What property of the structure of water allows water spiders to walk across the surface of a pond?
it is when water molecules in the water form a 'wall'.Pond skaters have legs that spread out away from their bodies, lowering the pressure exerted by their weight and not breaking the surface tension of the water
How do living things use surface tension?
Living things use surface tension to walk on water, by distributing their weight across the water's surface without breaking it. Some insects, like water striders, have adapted to take advantage of surface tension to move and survive on water. They also use it to trap and consume prey, by secreting sticky substances that immobilize their target.
What are the characteristics of a pond skater?
Pond skaters, also known as water striders, are insects characterized by their long, slender bodies and long legs, which allow them to walk on the surface of water without sinking. They possess a unique ability to use surface tension to support their weight, enabling them to glide effortlessly across ponds and streams. These insects are often dark brown or black in color and have compound eyes for keen vision. Additionally, pond skaters are predatory, feeding on small insects that fall onto the water's surface.
