Science Photo of the Day
How did this rock formation form?
Excellent! This is a Pahoehoe lava from at Craters of the Moon National Park in Idaho. Pahoehoe lava is very hot and fluid. This lava was starting to cool as it flowed. Its surface began to thicken and was folded by the moving liquid underneath. As it continued cooling, it hardened into this formation.
Pahoehoe is Hawaiian for "smooth, unbroken lava". Much of the groundwork for volcanic science has been done with the volcanoes in Hawaii, so many of the geologic terms are Hawaiian.

the rock may have been formed by the past in dinosaur time . It might mean that there was an ocean right there.
Where were you at at the time?

Hi Mr. Kramf,
I think that the rocks were formed by water and the water dissolved.
By the way I want to know how fast hummingbirds flap their wings? Are dolphins and seals endangered? How fast is a light year? And how big are the rock formations?
Your Admirer,
Jessica
Jessica from Mrs. Bottini's class
Depending on the species, hummingbirds can flap their wings up to 90 times per second.
Some species of dolphins and some species of seals are endangered.
A light year is the distance that light can travel in a year, which is 5,878,630,000,000 miles.
The rock formation in the photo is a lava flow that covers more than a mile.
Response from Mrs. Webber's class
Dear Mr. Krampf,
Most of us think that the rock was formed from molten rock. The lava must have moved down from the volcano and then dried up.
The rest of us believe that it was formed by erosion. The water moved over the rock, breaking it up, and forming the lines.
We look forward to finding out the answer. By the way, we really enjoy your beard!
Why are there plants growing in the rocks?
Your biggest fans,

RE: Response from Mrs. Webber's class
I'm glad you like my beard, because I really like it. I have had it since 1981, and have almost forgotten what I look like without it.
The plants on the rocks are growing in soil that the wind blew onto the rocks.

We think this was formed by lava.
Morgan from Ms.Webber's Class
Hello Mr. Krampf,
Well my guess is that a volcano erupted a long time ago and it formed into this rock off of a mountain.
What time of day should you see gecko's? Are there tiger sharks in the Bahama's? What other kind of animals can I see in the water around the Bahamas?
Your Admirer,
Morgan
Hi Morgan
Most geckos come out at night. Here in Florida, we see them around porch lights, hunting for insects.
Yes, there are Tiger Sharks in the Bahamas. In fact, there are tours where you can go diving to watch them, along with Hammerhead Sharks, Lemon Sharks, Spotted Dolphins, and many kinds of Reef Sharks.
