Systems of the Body
What are the two systems that work together to provide oxygen to cells and remove carbon dioxide?
The circulatory system & the respiratory system
What is the layer at the center of the Earth?
core / inner core
True or False:
Rocks don't ever change.
false
True or False:
There is always the same amount of water on the planet.
true
How many planets are in our solar system? Can you name them?
8: Mercury, Venus, Earth, Mars, Jupiter, Saturn , Uranus, Neptune
What is the muscle under the lungs that moves the lungs and causes a change in pressure?
Diaphragm
List and describe the type of plate boundaries.
Convergent = plates move together
Divergent = plates move apart
Transform = plates move alongside each other
**Subdution
Why can minerals not be identified by color alone?
Many minerals have similar colors/1 mineral can be multiple colors
What is the difference between climate and weather?
Weather: daily or short-term atmospheric conditions at a specific location
Climate: the long-term average of weather patterns in a region
What are the three states of water?
Solid (Ice), liquid (water), gas (steam/water vapor)
Where is blood made?
In bone marrow
Which boundary results in earthquakes?
transform boundary
Biologic sedimentary rocks are formed from______________.
dead things
What do we call the study of weather?
meteorolgy
What is precipitation:
rain/hail/sleet/snow
What is one function of the respiratory system?
Allows us to breathe
Works with the circulatory system to provide oxygen to cells and remove carbon dioxide
Describe the layers of the Earth.
-crust: outer most/ thinnest layer/ rigid
- mantle: dense/ hot layer/semi solid
- outer core: mostly liquid metal (iron + nickel)
- inner core: solid metal (mostly iron)
What happens when rocks melt, erode, or are put under intense pressure?
They transform into different types of rocks through the rock cycle.
Why are tropical climates in areas close to the equator?
Tropical climates are found in areas close to the equator because those regions have a lot of sunlight
What percentage of Earth's water is freshwater?
about 3 %
List the parts of blood and describe their importance.
Red Blood Cells: carry oxygen
White Blood Cells:guard against disease
Platelets:clot blood at a wound
Plasma:liquid that carries blood components
How is new crust formed on Earth's surface?
plates move apart + magma comes to surface to form new crust
List and describe the 3 types of rocks and how they are formed.
Igneous = formed by cooled lava or magma / found where volcanoes are common
Sedimentary = made of rock fragments / mineral crystals / dead things / found in rivers / streams / valleys
Metamorphic = rocks changed by extreme temperature or pressure
List the 5 elements of weather and describe them:
1. Temperature / measured w/ thermometer
2. Wind / measured w/ wind sock or wind vane
3. Humidity = moisture in the air
4. Precipitation = rain / hail / sleet / snow
5. Atmospheric pressure = weight of air / measured by barometer
What happens during the process of condensation in the water cycle?
Water gathers and cools in the atmosphere and returns to a liquid state when it is exposed to cooler temperatures.
