What method of dispersal is used by thistle and ash and maple seeds?
Thistle seeds use wind dispersal, with their small, feathery structures allowing them to be carried by the wind. Ash and maple seeds use a method called helicopter or autorotation dispersal, where their wing-like structures allow them to spin and glide through the air.
What are the four dispersal methods?
The four main dispersal methods are wind dispersal, water dispersal, animal dispersal, and self-dispersal. Wind dispersal involves seeds or spores being carried by the wind, water dispersal involves seeds or spores being carried by water currents, animal dispersal involves seeds or spores being carried by animals, and self-dispersal involves seeds or spores being dispersed by the plant itself.
What characteristics are necessary for mechanical dispersal of seeds?
Mechanical dispersal of seeds typically occurs through mechanisms like explosive seed pods, wind dispersal, or animal dispersal. Characteristics that aid in mechanical dispersal include lightweight seeds, winged structures for wind dispersal, or structures that allow for explosive release of seeds.
What are the agents of germination?
There are 5 main methods of seed dispersal. They are;- Wind dispersal- Gravity dispersal- Water dispersal- Animal dispersal (including humans!)- force dispersal

How far can ash travel from a fire and what factors influence its dispersal distance?
Ash from a fire can travel up to hundreds of miles depending on factors like wind speed, direction, and the size and intensity of the fire. Other factors include the type of vegetation burning and the presence of obstacles that can block or redirect the ash.
What are the agents of seeds dispersal?
wind dispersal, water dispersal, animal dispersal and mechanical dispersal
What the agents of the seeds?
wind dispersal, water dispersal, animal dispersal and mechanical dispersal
What happens when the upward energy of an eruption column decreases?
When the upward energy of an eruption column decreases, the volcanic ash and gases within the column can fall back to the ground. This can lead to pyroclastic flows, lahars, and ash fall in the surrounding areas. Decreased upward energy may also result in smaller eruption heights and less ash dispersal.
What are the four dispersal methods?

Wind dispersal involves seeds or spores being carried by the wind, water dispersal involves seeds or spores being carried by water currents, animal dispersal involves seeds or spores being carried by animals, and self-dispersal involves seeds or spores being dispersed by the plant itself.
What dispersal mean?
dispersal means to scatter about or to separate
What is the method of dispersal of a African tulip?
Wind dispersal
What is chance dispersal?
A means of dispersal that relies on chance.
How far did ash on the iceland volcano reach?
The ash from the recent volcanic eruptions in Iceland can travel significant distances, often reaching hundreds to thousands of kilometers depending on wind patterns and eruption intensity. For instance, during the 2010 Eyjafjallajökull eruption, ash clouds disrupted air travel across Europe, with ash reaching as far as the eastern United States. More recent eruptions have similarly resulted in ash dispersal affecting air traffic and air quality in surrounding regions. The exact distance varies with each event and environmental conditions.
