SKYQUEST

How far is it to the sky?

Hmmm.....

Good question!

Well, the Earth is surrounded by layers of gases we call air, or our atmosphere. The molecules, particles, and water droplets in the air can scatter sunlight, creating blue skies, red sunsets, and rainbows.

Earth's atmosphere is divided into multiple layers:

1. Troposphere begins at sea level

This is the lowest layer of the atmosphere and where we live so we know it best. It extends from sea level to an altitude of almost 12 miles above the equator, but only about 5 miles above the North and South poles. This is where weather takes shape. Planes fly in this layer.

2. Stratosphere is 12 miles/19 kilometers above sea level

This is where the ozone layer is located and where weather balloons gather information for meterologists.

3. Mesosphere is 30 miles/50 kilometers above sea level

This is where meteors appear and temperatures may be lower than -103 degrees F.

4. Thermosphere is 50 miles/80 kilometers above sea level

Space shuttles travel and the Aurora borealis/australis appear between this layer the exosphere.




Aurora australis




5. Exosphere is 250 miles/400 kilometers above sea level

At the bottom of this layer temperatures are below freezing. At the top
temperatures exceed 2200 degrees F/1200 degrees C. The ionosphere is
located here as well. The exosphere continues out into space until it
eventually merges with the atmosphere of the sun.

So, in answer to the question, I would have to say that the sky reaches upward to more than 250 miles above sea level, and since the first layer of our atmosphere is the troposphere, which begins at sea level, then that must be how far it is to the sky!

TULIPS

TULIP

GENUS: TULIPA

ANY OF VARIOUS BULB PLANTS OF THE LILY FAMILY, MOSTLY SPRING BLOOMING, WITH LONG, BROAD, POINTED LEAVES, AND, USUALLY, A SINGLE LARGE, CUP-SHAPED VARIOUSLY COLORED FLOWER.

NAMED FOR THE FLOWERS RESEMBLANCE TO A TURBAN.

EVER TIPTOE THROUGH THEM?
IT CAN BE FUN ESPECIALLY IF YOU SING WHILE DOING IT.

EVER WONDER HOW TULIPS KNOW WHEN TO BLOOM?

ME NEITHER, BUT I HAVE TO TELL YOU ANYWAY.

APPARENTLY THEY NEED 16 WEEKS OF COLD TEMPERATURES BEFORE ROOTS CAN DEVELOP FROM THE BULB AND ABSORB NUTRIENTS. TULIPS WILL NOT BLOOM WITHOUT THIS STAGE. THE BULB REQUIRES THIS "DOWN" TIME IN ORDER TO BE ABLE TO FLOURISH COME SPRING, THAT'S WHY THEY WON'T GROW OUTDOORS IN THE SOUTH. BUT THEY CAN BE FORCED ANY TIME OF YEAR AND EVEN MADE TO RE-BLOOM.

ADDITIONALLY, THEIR ORIGINS HAVE NOTHING TO DO THE NETHERLANDS. THEY ARE FROM ASIA. I FOUND THAT INTERESTING.


APPARENTLY I LIKE TULIPS.
