Natural Hazards
Name three natural hazards you know
Examples:
-earthquake
-tornado
-tsunami
What are some examples of natural resources?
Water, petroleum, minerals, forests, and animals.
In which ways do humans affect the environment?
Examples: Pollution, deforestation, global warming.
What does it depend on if it is daytime and nighttime?
They depend on where you are on Earth and the time of year.
What are some conditions that limit the design solution or that could prevent the solution from being accomplished referring to constraint?
Cost, time, size, laws
What is the term used for natural resources humans use to make objects or to eat as food?
Material resources
True or false: Human use of a resource may make that resource unavailable or unsuitable for other purposes.
True
True or false: The moon emit light of its own, the light we see is reflected is not from the Sun.
False.
The correct answer is: The moon does not emit any light of its own, the light we see is reflected from the Sun.
What is the difference between a natural hazard and a natural disaster?
A natural hazard is a natural phenomenon that may cause widespread injury, death, and property damage, while a natural disaster refers to these effects caused by a natural hazard.
Name three examples of energy ressources:
Examples:
-wind
-sunlight
-fossil fuels
How is solid waste divided?
It is divided in organic and inorganic
True or false: The position of the Earth as it moves around the Sun influences which stars are visible from our perspective on the planet at different times of the year.
True
What is the difference between weather and climate?
Weather describes the conditions in the atmosphere at any given time. On the other hand, climate describes long-term weather patterns.
What is the difference between renewable and non-renewable resources?
Renewable resources are natural resources that can be replaced at the same rate it is used, or faster, while non-renewable resources cannot be replaced as quickly as they are used.
True or false: Global climate is the result of complex interactions between the Earth’s systems driven by the energy from the sun.
False.
The correct answer is: Earth’s Climate System.
Name two seasons and their characteristics:
Example:
-Spring: The sun moves higher across the sky and the number of daylight hours increases.
-Summer: It is the warmest season, the sun is in the sky for a greater part of the day.
-Fall: Temperatures gradually cool.
-Winter: Freezing temperatures and snowfall are associated with winter months.
True or false: Mitigation refers to a statement that defines the type of solution that is required to address a need.
False.
The correct answer is: engineering design process.
Is it a long-term or short-term effect?
A nuclear energy accident results in immediate and permanent evacuation of a 20-mile radius because of radioactive contamination.
Long-term effect
What is the Greenhouse Effect?
It is the warming of the surface and lower atmosphere of Earth that occurs when greenhouse gases absorb and reradiate energy.
Name two types of eclipses and explain them:
Examples:
-total lunar eclipse: all the moon is covered by Earth’s shadow.
-partial lunar eclipse: only part of the moon is covered.
-total solar eclipse: when the Moon completely covers the face of the Sun - little halo of light
-annular solar eclipse: the Moon passes between the Sun and Earth, doesn’t completely cover it.
