Natural Hazards/Earth
Example of a natural hazard: full moon, earthquake, rainbow, or solar eclipse?
Earthquake
What is the main function of sensory receptors in the body?
To respond to stimuli
A cold front is approaching your area. What weather change is most likely to occur?
Cooler temperatures and possible storms
Which layer of rock is typically the oldest in an undisturbed sequence of sedimentary rocks?
The bottom layer
Which of the following best describes the water cycle?
Water circulates through evaporation, condensation, and precipitation
Which technology is most useful for warning people about approaching tsunamis?
Tsunami warning buoys
What do sensory receptors send to the brain when they detect a stimulus?
Messages
A warm, moist air mass meets a cold, dry air mass. What type of weather event is likely to occur at their boundary?
Storms and precipitation
What is the main force that causes weathering of rocks on Earth's surface?
Wind and water
What drives the cycling of water through earth's systems?
Energy from the sun and gravity
If a volcanic eruption adds new rock to Earth's surface, how does this affect the geologic time scale?
It creates a new layer that can be used to date events
How do cells in your stomach help your digestive system function?
They break down food and absorb nutrients
What is the purpose of collecting temperature, humidity, and wind speed data over several days?
To predict changes in weather conditions
Which process is responsible for the cycling of Earth's materials, such as rocks?
The rock cycle
Which process in the water cycle involves water vapor turning into liquid water?
Condensation
Which of the following is an example of geoscience process that changes Earth's surface over a short time scale?
Earthquake
Why do muscle cells have more mitochondria than skin cells?
Muscles need more energy for movement
What evidence does a student observing a temperature drop and clear sky after a cold front passes provide about air mass interactions?
Cold air masses bring clear, cool weather after passing
Which type of rock forms from cooling magma?
Igneous
Why is energy from the sun important in the water cycle?
It drives evaporation of water from Earth's surface
Which process is responsible for changing Earth's surface quickly, such as during a volcanic eruption?
Volcanic activity
Which statement best describes how the nervous systems work together to move your arm?
The nervous system sends signals to the muscles, causing them to contract
A weather map shows a low-pressure system moving into an area. What weather changes should residents expect, and why?
Cloudy skies and possible precipitation, because low pressure causes air to rise and cool
How does the rock cycle contribute to the recycling of Earth's materials?
Rocks change forms and materials are reused in new rocks
A model of the water cycle shows water evaporating from the ocean, forming clouds, and then falling as rain. What role does gravity play in this model?
It pulls rain from clouds to the ground
