How These Factors Effect Plants

Wind

Wind movement occurs due to the pressure on a global or local scale; the movement caused by differences in heating. At night, surface winds are less turbulent due to the absence of solar heating. When air is cool, it contracts, raising the pressure. When air warms, it expands and loses pressure. Whenever cool and warm air are in close proximity, the cold air flows towards the warm air or from high to low pressure to fix the imbalance of the pressure.

Temperature

The Effects of Global Warming On Plant Growth

Rainfall

The rise in temperature causes many plant species to grow in areas they are not normally found in. The temperature change also affects the ability for many plants to reproduce, reducing plant growth and diversity. The warmer temperatures promotes the expansion of forests into the tundra regions. This causes many species of plants in the tundra or arctic areas to become endangered because of the ground becoming warmer than they are accustomed to.

The increase in temperature warms the atmosphere, and the warmer air is able to trap more water vapour. This increases the amount of rainfall in wet areas, and the excessive amount of water can kill plants and makes the area vulnerable to floods. To balance the increased amount of rainfall, more evaporation occurs in dry areas, causing them to become drier.

Effects of Global Warming

Endangered Plant Species

Increase in:

- Temperature

- Rainfall

- Wind

An example of an endangered plant species in the tundra regions are the Bering Sea Douglasia. These plants flower at the end of June, growing pink or purple petals and extend to a height of about 2.5 inches. Unfortunately, due to the rapid rise in temperature, the Bering Sea Douglasia haven’t been able to adapt quickly enough, causing them to become endangered.

Coral Bleaching

What Is Global Warming?

Coral bleaching is when coral reefs get rid of the algae growing in their tissues when water gets too warm. The algae are the coral’s primary food source and also give coral reefs their colour. The outcome of this is the coral turning completely white, and this may kill off coral reefs. This also affects many animals, as coral reefs provide shelter for these animals and helps them avoid any prey. Coral Bleaching Infographic

Real Life Examples

Experiment

- We will be demostrating how negative environments influence plant growth using Cress Sprouts

Global warming is the increase in temperature on the earth's surface due to an increase in greenhouse gases.

Greenhouse gases are able to trap heat in the atmosphere, and the trapping of this heat is responsible for heating up the earths surface.

Greenhouse gases are composed mainly of water vapor, methane, carbon dioxide, nitrous oxide and ozone.
