Is the Earth my Giant Ice Cream Cone?

dreamstime_s_34523312

If I walk into an empty room and there’s a gigantic turtle sundae on the table, I’m going to eat it.

Really. I don’t care who made or where it came from, but I will sit down and enjoy every last bite. Only problem is that somebody did make it. And they probably won’t appreciate me scarfing down what they created. It was worth it, but later I’ll have to apologize for taking someone else’s ice cream, for using their creation to satisfy my own desires.

Many of us treat the Earth the same way. Like it’s our giant ice cream cone that appeared out of nowhere to fulfill our needs. Only problem is, Somebody created the earth and it’s a big Somebody.

If my tall husband were standing next to the turtle sundae telling me he made it, I’d be less likely to take it. Why? Because then I’d know to whom it belonged, plus he’s somebody I couldn’t easily elbow out of the way (although ice cream does make me a little dangerous).

My point is, when we think of the Earth as a cosmic accident—just one of many earth-like planets out there—it’s easy to abuse it and take what we want from it with no thought to the consequences. But when we understand who created this Earth (God) and how He lovingly formed each rock formation, each blade of grass, each ecosystem, we are overcome by awe.

No one except God saw the formation of the Earth. And He created it, not just so we would have a place to eat ice cream, but so we could cherish it like He does. How are you showing your respect and love for God by taking care of the Earth?

Wild Wind Farms

DSC00229

I’ve been going with my husband to visit his parents in their small town in north-central Iowa for about 18 years. In most of that time, few things have changed there, except for maybe the name of the town restaurant. But in the last few years, the landscape surrounding Wellsburg, Iowa has been transformed.

What was once flat farm land stretching to the horizon has turned into a series of giant wind farms. Sprouting from the fields like gargantuan corn stalks, the turbines stand hundreds of feet high, their propellers spinning with the constancy of a metronome. From a distance, it’s hard to gauge how high they really are or how fast they’re spinning. They seem to me all at once terrifying (what if one of those blades breaks off) and beautiful, especially at sunset. But then it doesn’t matter what I think. I’m not living next to one.

My in-laws aren’t living right next to one either, although they now have many turbines within two miles of their house. Because I’m insatiably curious, I did some research and found out some stuff you might not know:

  • Windmills have been in use since 2000 B.C. and were first developed in Persia and China
  • Modern wind turbines have 3 blades which can reach speeds at the tip of over 200 miles per hour
  • The largest wind turbine in the world is located in Hawaii and stands 20 stories tall with blades the length of a football field
  • A single wind turbine can power 500 homes
  • Wind power does not use any water, so by the year 2030 wind energy will save about 30 trillion bottles of water in the U.S.
  • As many as 1,300 eagles, falcons and hawks are killed each year due to wind turbines
  • By 2014, more than 46,000 wind turbines were in operation
  • There’s enough on-shore wind in America to power the country 10 times over

The magnificent wind is created by processes that God set up on our dynamic planet. He gave us the breeze for our enjoyment—to feel it blow through our hair on a hot day—but also for our use. We can be better stewards of our God given planet by investing in wind power.

What do you think? Do the benefits outweigh the costs (like dead birds, bats, noise, risk of airplanes hitting them) for developing wind energy?

Ice Quakes

????????????????????????????????????????????????????????????????

Ice Crystals

Anybody heard any sonic booms in the middle of this deep freeze? Maybe if you live in Florida or California or someplace outside the U.S., you don’t really care about those of us trapped in the swirling snow of the polar vortex, but much of the rest of this country has seen freezing temperatures on a record scale. And with those crazy temps comes a phenomenon that many have never heard of—ice quakes.

Called a cryoseism, it’s a cracking of the ground that comes from a sudden deep freezing of the water in the ground. Many times these quakes are heard as loud booms accompanied by a short-lived shaking. People have described them as sounding like a blown transformer, a sonic boom, a car accident and even a plane crash.

Ice quakes occur near the surface, so there’s no danger of prolonged shaking and little risk of property damage. If you want to hear one, they usually occur between midnight and dawn during the coldest part of the night. This explains why I’ve never heard one since I’m dead asleep at that time.

The explanation for ice quakes lies in the properties God gave to water. Unlike most liquids, water expands when it freezes because of the shape of the water molecule. If rain seeps down into cracks during warmer periods and then rapidly freezes when the temperature plummets, the ice expands and pushes on the surrounding material. Stress builds up until the pressure is released by the ground cracking.

Thanks to this frigid winter, ice quakes have been reported in the Midwest, Canada, the Northeast, and even parts of the south, like North Carolina and Tennessee. Ice quakes are nothing to be afraid of, but if a loud boom wakes you up in the middle of the night, I wouldn’t blame you if you called the police.

What about you? Have you actually heard one? What do you think it sounds like?

Blue Fire Volcano

Kawah Ijen

I’m constantly amazed at how God has created the world. There’s always something amazing to discover.

Like a blue fire volcano!

The volcano Kawah Ijen lies along a subduction zone in Indonesia. If you think of the earth as a baseball, the leather in the baseball represent the techtonic plates and the seams are where the plates meet. In a subduction zone, one plate slides under the other causing the rock on the lower plate to melt. This melted rock is more buoyant and rises to the surface, sometimes coming out in volcanic eruptions of lava and gas.

But Kawah Ijen has a special kind of volcanic display—blue fire. This blue phenomenon cascades down the volcano like lava, but it’s not blue lava. It’s actually rivers of sulfur. The sulfur gas escapes from cracks called fumeroles, hits the cooler air and some of it condenses into liquid sulfur.

When this sulfur ignites, it burns with blue fire (at up to 1,112°F) and appears to flow down the volcano like lava. Some of the flames reach as high as 16 feet.

This volcano generates so much sulfur that the local people mine it. They use spring water to condense the sulfur around ceramic pipes, which hardens it. Then these sulfur miners carry their rock load (usually 100 to 200 lbs of sulfur) down the volcano on their backs. What a way to make a living.

Diamonds of the Ocean Deep

???????????????????????????????????????????????????????????????????????????????????????????????????????????????????

 Anyone remember that scripture that says God opened the fountains of the deep when He initiated Noah’s flood? I know, I didn’t either. I had to look it up. Here it is:

In the six hundredth year of Noah’s life, on the seventeenth day of the second month—on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened.

Genesis 7:11

The reason I bring this up is because scientists have long suspected water exists deep in the molten core of our planet. And now they have evidence of it. Recently, geochemists have found a large quantity of molecular water hidden in of all things diamonds.

Diamonds have long been thought to originate from deep in the mantle and what we see today seems to confirm this. Minute specks of diamonds can be found coming out of currently active volcanoes.

In early 2014, Canadian geochemist Graham Pearson and his graduate student John McNeill found something unexpected in diamonds discovered at the edge of the Amazon rainforest. While shining a laser into the diamond, McNeill saw a rare mineral: ringwoodite (a variety of olivine formed after the mineral is put under great pressure). Previously seen only in meteorites, ringwoodite is thought to form in the dense interior of the earth, but until now no one could prove it.

As if that astounding discovery wasn’t enough, then McNeill noticed something even more unusual inside the ringwoodite structure—water. The water was trapped in the microscopic pore space of the mineral during formation, present not as liquid water but as hydroxide ions.

Although the amount of water in each ringwoodite mineral is small (1.5%), the mantle is vast—adding up to a huge amount of water held at high-pressure deep in the earth. The amount of trapped water is potentially close to all the water in Earth’s oceans.

When God said he released the springs of the great deep, perhaps He meant that He brought the hydroxide ions out of the chemical bonds of minerals stored in the mantle.

What do you think? Do you believe in Noah’s flood? Is it a surprise to know the mantle is full of water, even if only on a microscopic level?

WWII Fighter Jet Buried in Ice

 small_200496951

In 1942, a squadron of American fighter jets (six P-38s and two B-17s) took off from a secret base in Greenland. They were headed to England to join the fight against Hitler, but on the way over the polar ice cap, they ran into a blizzard. The whole squadron was forced to turn back.

By the time they reached Greenland again, the planes were low on fuel and had to make desperate crash landings on the icy east coast. All of the pilots survived and were rescued by dog sled nine days later. The planes, however, were abandoned for more than 45 years.

In 1988, U.S. airplane dealer Patrick Epps convinced his friend, architect Richard Taylor, to join an expedition to retrieve the planes. Epps thought they’d have to brush off a bit of snow and the aircrafts would be like new.

How wrong he was.

After several failed attempts at locating the aircrafts, Epps and Taylor hired a geophysicist to search beneath the ice. The radar indicated massive shapes more than 250 feet down.

Using a heated coil mechanism to melt the ice, they discovered all the missing planes. The fighters were found in the same orientation as when they crashed, but three miles from their original location (due to glacial flow).

Epps and Taylor had it in their mind that glacial ice builds up slowly because that’s what a gradual, slow-process view of the earth would expect. That was certainly not the case here. In 45 years, a mere blip of geologic time, 250 feet of ice had accumulated.

Without the WWII airplanes stuck in it, scientists would have claimed that same ice took thousands of years to form. Who says your world view doesn’t make a difference in your work as a scientist?
