Ques: Q: Geysers are created when what is heated beneath the earth's surface? Read this paragraph and choose the correct option from the provided answers: Geysers are also created by water that is heated beneath the Earth's surface. The water may become superheated by magma. It becomes trapped in a narrow passageway. The heat and pressure build as more water is added. When the pressure is too much, the superheated water bursts out onto the surface. This is a geyser . Choices: - magma - gases - air - water A:
Ans: water

Ques: Q: What do all respiratory diseases affect? Read this paragraph and choose the correct option from the provided answers: Reproduction Fungi reproduce sexually and/or asexually. Perfect fungi reproduce both sexually and asexually, while the so-called imperfect fungi reproduce only asexually (by mitosis). In both sexual and asexual reproduction, fungi produce spores that disperse from the parent organism by either floating on the wind or hitching a ride on an animal. Fungal spores are smaller and lighter than plant seeds. The giant puffball mushroom bursts open and releases trillions of spores. The huge number of spores released increases the likelihood of landing in an environment that will support growth (Figure 24.6). Choices: - liquid exchange process - helium exchange process - transit exchange process - gas exchange process A:
Ans: gas exchange process

Ques: Q: Scientists use the principles of what to make predictions, which they then test? Read this paragraph and choose the correct option from the provided answers: The experiment is a cornerstone in the scientific approach to gaining deeper knowledge about the natural world. Scientists use the principles of their hypothesis to make predictions, and then test them to see if their predictions are to be confirmed or rejected. Choices: - their teachers - their guesses - their faith - their hypothesis A:
Ans: their hypothesis

Ques: Q: What is the lowest layer of the atmosphere called? Read this paragraph and choose the correct option from the provided answers: Air movement takes place in the troposphere. This is the lowest layer of the atmosphere. Air moves because of differences in heating. These differences create convection currents and winds ( Figure below ). Choices: - mesosphere - lithosphere - asthenosphere - troposphere A:
Ans:
troposphere
