Algae do not necessarily have to float on top of the water. Some species of algae have adapted to their environment and actually live underwater so they do not have the risk of drying out. The surface algae though floats because it is not very dense (tightly packed) so it has air bubbles that allows it to float.
What else can I help you with?
Should a material have a higher or lower density to float in water?
A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel hull and the air inside the hull.
What is the analysis for can water float on water?
The ability for something to float on another substance is related to the density and since ice is LESS dense than water it would float on top of water, not water on top of ice.In other words, water is more dense than ice and thus no.
What will happen if oil mixed with warm water?
Not a lot, water and oil don't mix and so the oil will float on top of the water.
Tiny algae and animals that float in water?
Plankton :) I had the same question for science homework.
Is tent can float in water?
There are tents designed to Float in water. But not all tents designed to float.
What is algae's locomotion?
Algae float on the top of water and use photosynthesis. They all are producers and create glucose and oxygen.
When water and decane are mixed which layer will float on top?
Water is denser than decane, so the water layer will sink to the bottom while the decane layer will float on top.
What is the green stuff that floats on top of still water?
The green stuff that floats on top of still water is likely algae. Algae are small, plant-like organisms that can thrive in calm, nutrient-rich water. They can form a layer or a mat on the surface of the water, often giving it a greenish color.
Ice float on top of water?
Ice float on water because the density is lower.
Suppose you put a birthday caddle in a glass of water why will the caddle float on top of the water?
It will float on top because it is less dense than water.
Will diesel float or sink inwater?
Diesel will float on top of water because it has a lower density than water. This is due to the fact that diesel is less dense than water, which causes it to displace water and float on top.
Can helium float on top of water?
NO! be careful because in collage, my professor told my whole class that gases can float on top pf water.
Why does marimo weed float on a sunny day?
Marimo algae balls float on a sunny day due to the process of photosynthesis. When sunlight hits the algae, they produce oxygen gas that gets trapped on their surface, causing them to become buoyant and float to the water's surface. This allows the algae to receive maximum sunlight for photosynthesis.
What are organisms that float near the surface of fresh water lakes?
algae people dead fish
Can solid float on top of water?
yep
How does a ship stay on top of water?
a ship stays on water frombuoyancy which makes it float. the saltier the water the more buoyancy there is, enabling more weight to float on top
Can hot water float on top of cold water?
Yes
