Answer: The real tree house door should be 126 cm tall.
Explanation:
Given: Two students make a model of a tree house they want to build. The scale is 1:42.
i.e. 1 cm of model = 42 cm in real
if the in the scale model,the door is 3 cm tall, then the height of real tree house door = 3 x (42) cm
⇒ Height of real tree house door= 126 cm
Hence, the real tree house door should be 126 cm tall.

Answer:
The following is NOT part of the definition of a mineral: c. can be produced by natural or laboratory processes. Is glacial ice a mineral? d. Yes. Which type of bonds results when two atoms share electrons? d. Covalent
Explanation:
Mineral are composed of specific chemical elements. The are organized and their atomic structure forms crystals. They occur naturally and they are associated with rocks. The reason why they are inorganic is because they do not contain carbon, however, they can be produced by organic processes. Therefore, c. is NOT part of the definition of a mineral. Following the same principles, ice is considered a mineral because it is composed of one single chemical molecule (H2O), it occurs naturally and it contains a well organized crystal structure. The process of sharing two atoms is called covalent bond. In an ionic system, the electron is transferred to another atom so the concept of sharing is limited to the covalent bond.
Answer:
The sedimentary rock is a rock that has been made from other rocks that had existed in the Earth. The sedimentary rock has different layers of rock that can take form as gravel, stone, and maybe even a few gems inside.
Explanation:
The first step would be that the rock would be in liquid form, 2nd stage would be the sludge stage, which would contain both solids and liquids, then overtime, the sedimentary rock would form. The Sedimentary rock can also be made out of mud and sand that has been under countless pressure overtime. But you would be most able to find one near deserts, lakes, seas, and rivers. So bodies of water would give you the advantage to find this rock.
It is the Tigris River. The Tigris river is located at Asia. It is one of the major rivers in Asia.
