The ice sheets are the large masses of the glacial ice, which are spread more than 50,000 square kilometres. Ice sheath have maximum of the fresh waters, and they are also referred to as continental glaciers. The glacial ice less, which are less spread than ice sheets are known as ice caps. Many ice caps together form an ice field. These ice caps flows in all the directions outwards. only valley glaciers flow downwards in valley.
Hence, the correct answer is option (b). They flow in all the direction.
No, biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment. Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH.Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition... The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controling the biotic factors of an environment.
Answer: Yes, energy is required
Explanation:A selectively permeable membrane chooses which molecules are allowed to pass based on specific criteria (e.g., molecular geometry). This facilitated or active transport may require energy. Semipermeability can apply to both natural and synthetic materials. In addition to membranes, fibers may also be semipermeable.
Through the action of force. Gravitational force- when gravity accelerates a falling object, it converted its potential energy to Kinect energy
