How is the tree changing so that it continues to grow upright?

How is the tree changing so that it continues to grow upright?

Trees (and most other plants) detect gravity using tiny structures within the cells of their roots and shoots called ‘statoliths’, which tell them which way is up (a process known as ‘gravitropism’). The tree would then use this information to re-orient itself and continue to grow its shoots vertically.

What agent of erosion is slowly moving the tree down the hillside?

Creep is the very slow movement of rock and soil down a hillside. Creep occurs so slowly you can’t see it happening. You can only see the effects of creep after years of movement (Figure below). The slowly moving ground causes trees, fence posts, and other structures on the surface to tilt downhill.

Why can Loess travel further than sand?

Loess can be carried further than sand because loess ways less than sand so wind can pick loess up easier.

How does wind and glaciers abrade rock?

Wind abrades rock by sandblasting, this is the process in which wind causes the blowing of millions of grains of sand, which bumps across the surface of rocks’ surface. As glaciers move forwad, the material that they picked up scratch and abrade the rock and soil underneath the glacier, which causes erosion.

Which trees grow straight up?

7 Fast Growing Trees in India

  • Sagwan Tree. Goes by the name Teak, it additionally holds therapeutic worth.
  • Nimboo. Indian Elm or Dhauranjo is a huge deciduous tree, growing up to 18 m tall.
  • Ber.
  • Babool.
  • Neem.
  • Amrood/Jamphal.
  • Mahua.

How are trees so strong?

The presence of wind makes a tree stronger, it is thus able to mature and not fall down due to its own weight. When plants and trees grow in the wild, the wind constantly keeps them moving. So, to compensate, the tree manages to grow something called the reaction wood (or stress wood).

What is the strongest agent of erosion?

Liquid water is the major agent of erosion on Earth.

What increases the size of particles carried increases?

The average velocity (speed) of a stream depends on its slope and discharge, which in turn can explain the carrying power of a stream. o As velocity of the stream water increases, size of the particles carried in the stream also increases, a direct relationship.

How is loess different from sand?

How do loess deposits differ from sand deposits? -Some of the loess in loess deposits has come from glacial outwash deposits, whereas sand in sand deposits does not come from glacial outwash deposits. -Sand deposits are made of larger grains than loess deposits, which are made of silt-sized grains.

Is wind the strongest or weakest agent of erosion?

Wind by itself is the weakest agent of erosion. Water, waves, mov- ing ice, and even mass movement have more effect on the land. Larger particles slide or roll. removes surface materials.

When wind moves soil sand and rock particles it acts as an agent of?

Erosion by Wind Wind is a powerful agent of erosion. Aeolian (wind-driven) processes constantly transport dust, sand, and ash from one place to another.

Were in North America would you expect to find glaciers?

Most U.S. glaciers are in Alaska; others can be found in Washington, Oregon, California, Montana, Wyoming, Colorado, and Nevada (Wheeler Peak Glacier in Great Basin National Park).

Can a tree be planted on a hill?

Trees on a hill break up the landscape and can provide a buffer against wind. However, compared to using a flat planting site, access to the tree may be more tricky when grown on a slope.

Is it good to grow trees on a slope?

Sloping ground can help soil to become well-drained, promoting tree growth; however, careful preparation is necessary to make sure the soil is only draining and not eroding away. Trees on a hill break up the landscape and can provide a buffer against wind.

What should I do if my soil gradient is too high?

High gradients increase the risk of significant soil erosion around your tree. Use your soil testing kit to measure the pH of the soil at your planting site. If the pH is higher than desired for the type of tree you are planting, apply sulfur or aluminum sulfate to bring the pH down.
