Due to the unusually strong cohesive forces between water molecules, water has an unusually high surface tension. Water striders take advantage of this surface tension by "walking" over the water and able to not break through the surface of the water. As a classic example of form fits function, the light body weight and thin legs of the water strider further aid it in doing this.
Water striders can slide over the surface of water due to their hydrophobic (water-repelling) legs and their small body weight. This combination allows them to distribute their weight over a larger area, creating enough surface tension to support their weight and move across the water's surface.

What makes raindrops slide on glass?
Raindrops slide on glass because of the surface tension of water, which causes the water molecules to stick together and creates a thin film over the glass surface. Additionally, the smooth surface of glass provides little resistance for the raindrops to move across it easily.
Can a water slide produce thermal energy with friction?
Yes, a water slide can produce thermal energy through friction. As riders slide down the slide, the friction between their bodies and the slide surface generates heat energy. This heat energy increases the temperature of the slide and the water running down it.
What is the thin glass square called that is placed over a microscope slide called?
The thin glass square that is placed over a microscope slide is called a cover slip. It is used to protect the specimen on the slide and to provide a flat surface for viewing under the microscope.
What are waves called that travel on the surface of the water?
Waves that travel on the surface of the water are called surface waves. These waves are created by wind blowing over the water, causing the surface to rise and fall in a rolling motion.
What is the difference between slide and glide?
In general usage, "slide" typically implies movement along a smooth surface, while "glide" suggests a smooth and effortless movement through the air or over a surface. Slide can also involve a more friction-based movement, whereas glide is often associated with a more graceful or elegant motion.
How do water striders walk on water?
Water striders use their long legs and low body weight to distribute their weight over a large surface area, allowing them to effectively "skate" on the water's surface tension. This surface tension is created by the cohesive forces between water molecules, which are strong enough to support the water strider's weight without breaking. Their specialized hydrophobic legs also help repel water, preventing them from sinking.
What makes raindrops slide on glass?
Raindrops slide on glass because of the surface tension of water, which causes the water molecules to stick together and creates a thin film over the glass surface. Additionally, the smooth surface of glass provides little resistance for the raindrops to move across it easily.
How can a mosquito walk on water?
There are several insects that can walk on water due to the water's surface tension. There are over 300 species of water striders that are able to walk on water, as well as several species of ant.
Can a water slide produce thermal energy with friction?
Yes, a water slide can produce thermal energy through friction. As riders slide down the slide, the friction between their bodies and the slide surface generates heat energy. This heat energy increases the temperature of the slide and the water running down it.
Why is water surface tension important for organisms?
Water surface tension is important for organisms because it allows small aquatic insects to walk on the surface of water without sinking, and helps certain animals like water striders to glide over the water. It also enables plants like water lilies to stay afloat and helps with capillary action in plants, which aids in the transport of water and nutrients.
When observing a slide should the specimen be on the top or bottom surface of the microscope?
The specimen should be placed on the top surface of the microscope slide. This allows the light to pass through the specimen from below and be magnified by the lenses in the microscope to form an image for observation.
What is the water called when it runs over ground?
Surface water.
When solid surface slide over each other the kind of friction that occurs is called blank friction?
sliding
How much of the earth surface us covered by water?
Over 70% of the Earth's surface is covered with water
What is the thin glass square called that is placed over a microscope slide called?
The thin glass square that is placed over a microscope slide is called a cover slip. It is used to protect the specimen on the slide and to provide a flat surface for viewing under the microscope.
Does earth have availability of water?
Yes, it its surface is over 70% water.
What is water that flows over earth's surface?
Water that flows over Earth's surface is called surface water. It can come from sources like rivers, lakes, streams, and oceans, and plays a crucial role in shaping the landscape and supporting ecosystems. Surface water can also be a source of drinking water and energy generation.
