What change is when the tiny pieces that make up a substance rearrange themselves to form completely new substances with different properties.?
What is a chemical change
If the Earth's axis tilt changes which of the following would be effected?
A. Wind Speed over the Earth's surface
B. The seasons on the Earth's surface would change
C. The amount of solar energy the Earth absorbs.
B. The seasons on the Earth's surface would change
A wet air mass near the equator moves into a cold and dry area? What will happen to the temperature in that area?
The temperature will increase become hotter and the area will become more wet.
What kind of house would survive better from an earthquake.
A. A house made of straw
B. A house made of sticks
C. A house made of bricks
C. A house made of bricks.
It would be more stable in the case of a earthquake.
Human activity have caused a big effect to global warming. What caused this?
Human activity causes global warming primarily by releasing heat-trapping greenhouse gases, like carbon dioxide, into the atmosphere through the burning of fossil fuels.
Which has the most kinetic energy?
A. Solid
B. Liquid
C. Gas
Sunflowers need to photosynthesis to grow. If there was more dissolved oxygen in location A after a month than location B, Which location would the sunflowers grow better in?
Location A. Sunflowers need to complete the process of photosynthesis to grow. Oxygen is a product of photosynthesis. The more the sunflower photosynthesis, the more oxygen would be left in the air.
water + carbon dioxide + light energy = sugar + oxygen.
When two air masses collide, what type of weather event is most likely to occur?
rain / precipitation / thunderstorm
Where do hurricanes normally form?
over warm waters
Scientists recorded that over the past 50 years, the annual amount of CO2 in the atmosphere has increased by at least 100ppm.
In the past, over 10 million years, the amount of CO2 had decreased by 1,000ppm.
How would you compare the amount of CO2 in the atmosphere from the past to now? Draw what the data would look like Now v. in the past.
The amount of CO2 now has increased significantly so the data would show a steep upward slope
In the it slowly decreased over time, so it would show a small slope in the opposite direction
What organism consumes plants and animals?
Omnivores
What water cycle process transforms a liquid into a gas?
Evaporation from water to gas or Transpiration from trees (water) to gas
What is the temperature and the precipitation like near the equator?
Hot and wet.
Which two Earth spheres are the most directly involved in the formation and power of a hurricane?
The hydrosphere and the atmosphere
This is what happens to Earth's overall temperature when too many greenhouse gases are trapped in the atmosphere, making polar ice melt.
What is global warming
During chemical reactions, one reactant becomes one product. If a reactant has a weight of 15 lbs, What is the weight of the product?
15 lbs. 1 reactant = 1 product during chemical reactions the reactants = products
What water cycle process causes cloud form?
Condensation
What is a rain shadow?
A rain shadow is a dry area on the side of a mountain that is sheltered from rain-bearing winds, because the mountain blocks the rain from reaching it.
When a hurricane hits land, what happens to its speed and moisture?
They both will decrease
When we burn coal, oil, and natural gas for electricity and cars, this main greenhouse gas goes into the air.
What is Carbon Dioxide
Which of the following describes a physical change?
A. A log burning in a campfire.
B. An iron nail turning reddish-brown over time.
C. A person ripping a piece of glass into many smaller bits of paper
D. Food being digested in your stomach.
C. A person ripping a piece of glass into many smaller bits of paper
When vegetation is added to the side of a hill, how would that affect infiltration and runoff?
Decrease runoff and increase infiltration. More plants more infiltration.
How are temperature and moisture affected by how close a city is to the water?
What are the Cities near water are cooler and wetter
What are the main factors that affect a landslide?
A. Gravity of the falling soil and rock.
B. Wind Speed of the air.
C. Movement of glacial ice.
A. Gravity and falling soil and rock
Water Vapor is a greenhouse gas that is produced by burning fossil fuels. How long does water vapor stay the atmosphere and why?
A short amount of time. Around 0-1 weeks. It is led back to earth as rain.
