Plate tectonics and Rock Cycling
What type of plate movement is at a convergent plate boundary?
Move into each other.
Where do tsunamis occur?
Tsunamis occur in the ocean
Describe an exothermic reaction, how would it feel.
It is a chemical reaction that releases energy to its surroundings making it feel hot.
Define criteria
Criteria are the requirements that a design solution must meet.
What occurs at plate boundaries?
Earthquakes and Landslides.
What is the purpose of a tsunami warning system?
Give the earliest possible warning so people can move to higher ground.
Decribe an endothermic reaction, how would it feel?
A chemical reaction that absorbs heat from its surroundings making it feel cold.
Define constraints.
Constraints are the limitations or restrictions in a design.
What kind of plate motion moved Africa and South America apart and what did it make?
Divergent, Mid-Ocean Ridge
What groups are most at risk during natural hazards?
Groups that are children, the elderly, the handicapped, and people who speak different languages.
What are signs that a chemical reaction has occurred?
Bubbling, fizzing, temperature change, color change, change in order, precipate
Identify the independent, dependent, and control variables in the following scenario: Scientists monitored the rainfall levels at a research station every day in the mont of April.
Independent variable: Different days in April
Dependent variable: Amount of rainfall
Control variables: Resaerch station, same rain gauge, same location at station
What provides evidence of past plate movements?
Fossils, Rock Layers, and Continent Shapes
What happens to energy from the tsunami wave as it reaches shore?
The waves get taller due to the shallow ocean floor and energy gets transferred to the land when it hits shore
What happens to the arrangement of the molecules during a chemical reaction?
The molecules in the reactants get rearranged to create new products.
What are the steps in engineering design?
Clearly identify the problem, criteria, and constraints. Generate possible solutions to the problem. Implement the design and test the results. Analyze the data to select the best solution. Accept the solution or redesign the solution.
Convection Currents in the mantle cause plate motion. Where in the cycle would the rock become heated and where in the cycle would the rock cool down?
The rock heats when it touches the outer core. The rock cools as it rises and touches the cooler crust.
What parts of the U.S are most at risk against tornadoes?
The middle section of the U.S is at most risk for tornadoes.
