W
What does W stand for and what state of matter does it have to be in?
water (liquid)
Moons
What does T stand for?
Temperature
What does E stand for?
Energy!
What does N stand for?
Nutrients
True or false: liquid water is something that everything living cell needs and is probably the most important thing
Our atmosphere burns up most of these before they can hit the earth.
Meteors
What most determines the temperature of a planet? (what makes a planet hot or cold?)
Distance from the star/sun (closer=hotter and further=colder)
What serves as the source of energy for organisms that can do photosynthesis?
Sunlight
What are nutrients?
Any chemical (element or compound) that our bodies needs to work correctly
Water is so important because it helps ___________ and __________ important chemicals around a cell, our bodies, and around the earth itself.
dissolve and transport/deliver/move
Our atmosphere protects us from this kind of radiation from the sun.
Ultraviolet Radiation (UV)
What is the zone called that is the correct distance away from a star for water to be a good temperature to stay liquid?
Habitable zone or Goldilocks zone
What type of energy do humans use when we eat our food?
Give an example of a nutrient that humans need.
Iron, calcium, protein, magnesium, Vitamin C, carbohydrates, amino acids, phosphorus etc...
What is the chemical formula for water? How many total atoms are in a molecule of water?
H2O= 2 hydrogens + 1 oxygen for a total of 3 atoms
We say that our atmosphere helps insulate our earth. What does insulate mean?
keep warm, act as a blanket, trap heat
What happens to the habitable zone if the star is larger?
The habitable zone will be further away from the star since its light/heat can travel further
What can energy help cells do?
Repair itself, reproduce/multiply, chemical reactions it needs to stay alive
Where are nutrients stored here on Earth?
In the soil! The plants then absorb them from their roots and animals can eat the plants
An average cell (smallest part of a living thing) is made up of about how much water?
70%
Describe what would happen to our atmosphere if earth had more mass or less mass.
More mass= more gravity= thicker atmosphere=hotter temperatures
Less mass=less gravity=no atmosphere= no protection or insulation
It is important for the temperatures to be just right so the water can remain a liquid (not freeze or evaporate), but too hot and too cold is bad for living cells as well. What happens to a cell that experiences too high of temperatures?
The DNA and proteins break down and the cell dies
True or false: If we did not have enough light energy from the sun, only the plants would be affected.
False- consumers rely on plants to eat as chemical energy
It is not enough for a planet to just have nutrients, it also needs to have a way to cycle/move them. What are three ways our Earth can cycle and move nutrients around?
Water Cycle, Plate Tectonics, Volcanic eruptions
