Cloud the bottom of the hierarchy. Clouds in the troposphere assume five physical forms based on structure and process of formation. These forms are commonly used for the purpose of satellite analysis. They are given below in approximate ascending order of instability or convective activity. "Non-convective" stratiform clouds appear in "stable" airmass conditions and, in general, have flat sheet-like structures that can form at any altitude in the troposphere. The stratiform group is divided by altitude range into the genera cirrostratus (high-level), altostratus (mid-level), stratus (low-level), and nimbostratus (multi-level). Fog is commonly considered a surface-based cloud layer. The fog may form
Term sheet founders and venture capitalists: Term sheet A term sheet is a bullet-point document outlining the material terms and conditions of a business agreement. After a term sheet has been "executed", it guides legal counsel in the preparation of a proposed "final agreement". It then guides, but is not necessarily binding, as the signatories negotiate, usually with legal counsel, the final terms of their agreement. A term sheet implies the conditions of a business transaction, as proposed by a party. It may be either binding or non-binding. Term sheets are very similar to "letters of intent" (LOI) in that they are
