- Q1If the density of liquid water is less than the density of ice, what would happen to the oceans during extremely cold weather?The oceans will be covered by fog and clouds.The oceans will remain liquid without changing in temperature.The oceans will completely freeze.The oceans will evaporate into the atmosphere.120s
- Q2Why is the atmosphere important in hydrological cycle?The atmosphere releases a huge amount of water in the form of water vapor.The air in the atmosphere carries water to different areas.Several layers of the atmosphere are involved in the hydrological cycle.All forms of water can be carried by the air in the atmosphere.120s
- Q3How does the biosphere influence the atmosphere and climate?By using all the space left on land, water and air as habitatBy taking part in photosynthesis allowing exchange of oxygen and carbon dioxideBy undergoing respiration which allows exchange of gasesBy moving from one sphere to another120s
- Q4How does wind erosion affect the climate?Dust from land may mix with water changing the temperature of different bodies of water.The wind serves as the medium of transport of energy from the dust particles to the greenhouse gases.The wind carries the greenhouse gases trapped in the dust particles.Dust from land may be blown into the atmosphere and may interact with the radiation.120s
- Q5Quartz displays conchoidal fracture, often seen as smooth shell-like curves, instead of a perfect cleavage plane. Which of the following statements best explains this property?It shows that the atomic bonding of the mineral is weak.It shows that the mineral is very soft creating smooth curves.It shows that mineral crystallizes at low temperature.It shows that the there are no planes of weakness inside the mineral.120s
- Q6Where do sediments come from?Sediments are results of high temperature and pressure within the Earth’s interior.Sediments are products of weathering and transported by glaciers, wind, and streams.Sediments come directly from the crystallization of magma from the Earth’s interior.Sediments are results from varying mineral composition.120s
- Q7Which of the following statements best explains why a metamorphic rock can change into another metamorphic rock?Metamorphic rock may rise to the surface through magma and might undergo change in composition as it reaches the Earth’s surface.A metamorphic rock may melt and begin to crystallize as it move towards the Earth’s surface.Low grade metamorphism might create a metamorphic rock and as it experiences changes in temperature-pressure conditions, another metamorphic rock may form.Metamorphic rocks may undergo weathering and and as sediments are transported and deposited, it may eventually form another metamorphic rock.120s
- Q8Arrange the following steps of fertilization.Users re-arrange answers into correct orderJumble120s
- Q9Arrange the following levels of organization from the simplest to the most complex.Users re-arrange answers into correct orderJumble120s
- Q10What was the importance of photosynthesis in the evolution of lifeforms?Photosynthesis produced more oxygen that allowed oxygen-breathing organisms to exist.Photosynthesis increased the amount of carbon dioxide allowing plants to proliferate and evolve.Photosynthesis allowed all eukaryotes to make their own food.Photosynthesis used up energy from the sun to warm the atmosphere.120s
