Air that moves horizontally between high and low pressure zones makes wind. The greater the pressure difference between the pressure zones the faster the wind moves. Convection in the atmosphere creates the planet's weather.
Hope that helps:)
By process of elimination you can find the right answer. We know for a fact that carbon is found in all living organisms. That is why we talk about carbon based life forms. So the first statement cannot be true. You can figure out how many Valence electrons an element has by looking at the group number. The group number of carbon is 4 so the 2nd statement cannot be true. We know that carbon does bond with other elements because it is not a noble gas and therefore must be able to form compounds.
This means the answer must be they can form up to four covalent bonds
Answer: Malignant tumor-
cancer cells are contained within their tissue.
Maglinant tumor-- Cells of this type of tumors have the potential to , escaping their tissue and spreading to other locations within the body.
Benign tumour-pre-cancerous cells highly disorganized metastasize.
Explanation: Tumor is an abnormal growth in the cell.
Benign tumor is a tumor that do not spread within the cell and are not cancerous. The can grow to very large and are removed by operation. It can be very dangerous when its big and press other tissues especially when located in the brain. It may not require any treatment when it is not threatening. Example of benign is fibroid
Malignant tumour are tumour that are cancerous and can spread to other tissues. They can be transported via the blood stream to other tissues. Malignant tumour grows fast and can spread to nearby tissues example is breast cancer when not diagonize earlier can spread to other tissues. They required medical attention and can be removed through operation, some require chemotheraphy. Some malignant tumour grows back even after removal.

The answer is probably Boiling.
Endothermic process or reaction refers to the system in which the heat energy is absorbed from the surroundings. In boiling, the evaporation of the liquid water is an example of an endothermic process. Other examples are photosynthesis, the melting of ice, and cracking of alkanes.
