a bristlecone pine in the white house usually adds a new ring when which of the following occurs?
a. earths daily rotation is complete
b. the full moon causes a monthly high tide
c. the new moon is visible from earths surface
d. earths northern hemisphere is titled toward the sun
a bristlecone pine in the white house
A WHAT? WHERE?
oops i meant white mountains
thanks
You're welcome.
To determine which of the options is the correct answer, we need to understand the growth pattern of a bristlecone pine tree. Bristlecone pines are known for their slow growth and long lifespan. They add a new ring to their trunk each year, as they grow a little bit each year during suitable conditions.
Now, let's analyze each of the options to determine which one leads to the formation of a new ring:
a. Earth's daily rotation is complete: This option refers to the completion of Earth's rotation in a 24-hour period. However, the daily rotation of the Earth does not directly impact the growth of trees. Therefore, this option is not the correct answer.
b. The full moon causes a monthly high tide: The full moon is associated with high tides on Earth due to the gravitational pull of the moon. However, tides and moon phases do not affect the growth of bristlecone pine trees. Therefore, this option is not the correct answer.
c. The new moon is visible from Earth's surface: The new moon is a lunar phase where the moon is not visible from Earth. While lunar phases have an impact on various natural processes, the visibility of the new moon does not directly influence the growth of bristlecone pine trees. Therefore, this option is not the correct answer.
d. Earth's northern hemisphere is tilted toward the sun: This option refers to the tilt of the Earth's axis, which causes the change of seasons. Bristlecone pine trees, like many other plants, are responsive to the changing seasons, as they grow during favorable conditions. The tilt of the Earth's northern hemisphere toward the sun determines the onset of spring and the availability of sunlight, which promotes growth in plants. Therefore, the correct answer is option d.
In conclusion, a bristlecone pine in the White House usually adds a new ring when Earth's northern hemisphere is tilted toward the sun (option d). This occurs during the onset of spring, indicating favorable conditions for growth.
