Answer: Length, Shape and density of an object do not necessarily determine the shape of a crater
Explanation: a crater is a rough opening on a solid surface, it might be circular or any shape. The major factor that determines the shape of a crater is the mass and velocity of the impactor like the meteorite. When an impactor hits a solid surface, it breaks out in all director irrespective of the shape of the impactor. We have simple and complex craters depending on the impact strength.
Answer:
A high pressure system works downwards and brings with it good weather, while a low pressure system works upwards and brings bad weather. Due to the Earth’s rotation and friction on its surface, air currents are formed. When these currents move clockwise and out of the center, a space is formed at the center. The land quickly loses its heat whiles the water retains its warmth. That means the air over the water is warmer, less dense, and begins to rise. Low pressure is created over the water. Cold and dense air over the land begins to move to the water surface to replace the warmer rising air. The cool breeze from the land is called a land breeze.
Explanation:
Diffusion is a process that occurs when a substance such as water, molecules, and ions, which are usually needed for various cellular processes, enter and leave cells. The way that cell diffusion happens is by molecules moving from an area of high concentration to an area of low concentration. This usually occurs until both molecules have the same amount of the substance and it is distributed evenly.
