High humidity is the main cause of high temperatures and the abundant rainfall.
SOIL
THE GENERAL ASSUMPTION:
The abundant of rich habitats come from fertile soil!
WRONG!
Tropical rainforests grow in nutrient-poor soil which is only two to three inches deep.
THEN WHY?
The roots of many plants spread over large areas quickly capture nutrie
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

1. Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas.

saturated liquid and vapor volume as well as using the general formulas
of the three gas laws. There are 7 graphs which plotted based on the
pressure and volume (PV) calculation and lastly a 3D graph showing
the relationshipsof temperature, pressure and volume. All these graphs
are plotted using the Matlab program.
Through this design project, we find tha

The atmosphere can be divided vertically into four major layers : troposphere, stratosphere, mesosphere, and thermosphere.
Figure 2.1 The earth’s atmosphere is subdivided vertically into four major regions based on the air-temperature profile. The ozone layer that protects us from the sun’s UV radiation is in the stratosphere.

1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine

temperatures (about 700°C or 1300°F). The reactors also resist attack by hydrogen gases which can corrode many metals, especially at high temperature and pressure. The catalyst in commercial ammonia synthesis is usually an iron oxide mixed with a small amount of additional "promoter" material. When the process begins, the hydrogen gas converts the catalyst to pure iron. Gradually, as the iron c
(1) What Is A Tropical Rainforest?
In general, a rainforest is a forested area that receives over 60 inches of rain per year.
1. Climate: High humidity is the main cause of high temperatures and the abundant rainfall.
2. Soil: Tropical rainforests grow in nutrient-poor soil and more nutrients are found in the living plants of the rainforest than in the supporting environment.

According to a 'threat paper' on Kuwait produced in secret by the UK Atomic Energy Authority and subsequently leaked, 50 tonnes of DU inhaled could cause up to half a million additional cancer deaths over several decades, a
