Air pressure is the pressure in a given area caused by the weight of the atmosphere pressing down on that area. The column of air that extends above an area contains the weight of all of the molecules above that area. (This invisible column extends up through all the levels of the atmosphere.) For this reason, altitude affects air pressure. The column of air that extends from the bottom of the ocean (sea level) is very tall, with the weight of the whole atmosphere pressing on it. Consequently, the air pressure at sea level is high. The opposite is true at a high altitude, such as at the top of Mount Everest. There, the column of air pressing down is shorter, so air pressure is lower.
Which cause = effect is correct?
Cause - Altitude is lower, such as at sea level
Effect - Air pressure is higher.
Cause - Altitude is lower, such as at sea level
Effect - Air pressure is lower. .
Cause - Altitude is higher, such as at top of Mount Everest.
Effect - Air pressure is higher.
Cause - Altitude is higher, such as at top of Mount Everest.

You have probably heard of the pH scale, which measures how acidic or basic different solutions are. A solution's acidity or basicity is related to its concentrations of hydronium ions and hydroxide ions. When a strong acid is added to a solution, atoms in the solution break apart to form hydronium ions. This leads to a more acidic solution. When a strong base is added to a solution, atoms in the solution break apart to form hydroxide ions. This results in a more basic solution.
Which cause = effect is correct?
Cause - Hydronium ions form in the solution.
Effect - The solution becomes more acidic.
Cause - Hydronium ions form in the solution.
Effect - The solution becomes more basic.
Cause - Hydroxide ions form in the solution.
Effect - The solution becomes more acidic.
Cause - Hydroxide ions form in the solution.
Effect - The solution becomes more basic.

The respiratory system is composed of airways, lungs, blood vessels, and muscles working together to supply oxygen to all parts of your body. The diaphragm, a muscle located beneath the lungs, plays an important role. When you inhale, the diaphragm squeezes, or contracts, and moves downward. As a consequence, there is more room for the lungs to expand as they fill with air. When you exhale, the diaphragm relaxes and moves upward, which leads to air being pushed out of the lungs.
Which cause = effect is correct?
Cause - The diaphragm contracts and moves downward.
Effect - Air moves out of the lungs.
Cause - The diaphragm contracts and moves downward.
Effect - Air moves into of the lung.
Cause - The diaphragm relaxes and moves upward.
Effect - Air moves out of the lungs.
Cause - The diaphragm relaxes and moves upward.
Effect - Air moves into of the lungs.

Black mambas are fast, aggressive, and venomous. It's no wonder that they're considered the world's deadliest snake. In general, the snakes actually try to avoid confrontation. However, a perceived threat to a black mamba will result in several reactions meant to warn a potential victim. First, the black mamba raises its head, spreads out its neck-flap, opens its black mouth, and hisses. A threat that continues will lead to a more dangerous reaction: the mamba will bite its victim repeatedly, injecting its poisonous venom. For most of history, a mamba bite would mean certain death. Today, though, an effective antivenom is available.
Which cause = effect is correct?
Cause - Black mamba perceives a new threat.
Effect - Black mamba injects victim with venom.
Cause - Black mamba perceives a new threat.
Effect - Black mamba hisses.
Cause - Black mamba perceives a continuing threat.
Effect - Black mamba injects victim with venom.
Cause - Black mamba perceives a continuing threat.
Effect - Black mamba hisses.

George Lucas directed and co-wrote the 1973 film American Graffiti, a classic coming-of-age tale set in Northern California. The film cost less than eight hundred thousand dollars to produce but earned more than two hundred million dollars. Because the film was such a huge success, 20th Century Fox agreed to finance Lucas's next project. Star Wars was released on May 25, 1977, and became an instant box-office hit. The film's huge success resulted in the production of two sequels: The Empire Strikes Back and Return of the Jedi.
Which cause = effect is correct?
Cause - Star Wars was a hit.
Effect - 20th Century Fox committed money for Lucas's next film.
Cause - Star Wars was a hit.
Effect - Two sequels were produced.
Cause - American Graffiti was a hit.
Effect - 20th Century Fox committed money for Lucas's next film.
.Cause - American Graffiti was a hit.

Since 2013, the population of sea stars along North America's Pacific Coast has been dramatically reduced. Microbiologist Ian Hewson believes a type of virus known as Sea Star Association Densovirus (SSaDV) is responsible. Due to the disease, sea stars eventually decompose into a white sludge. Surprisingly, though, hundreds of sea star babies appeared in the spring of 2016 along the Oregon coast. Researchers think that the massive reduction in adult sea stars has contributed to the baby boom. Fewer hungry adult sea stars means more food for hungry babies. In turn, more food has led to a greater survival rate for the youngsters.
Which cause = effect is correct?
Cause - More food is available.
Effect - Sea Stars are disintegrating into white goo.
Cause - More food is available.
Effect - More sea star babies are surviving.
Cause - Sea stars are getting SSaDV.
Effect - Sea Stars are disintegrating into white goo.
Cause - Sea stars are getting SSaDV.
Effect - More sea star babies are surviving.

For years, fishermen in Bali used dynamite and cyanide to catch fish, which had the effect of destroying coral reefs in the area. In 2000, though, the Biorock reef restoration project began. Under normal conditions, a reef forms when polyps put down layers of calcium carbonate. In the Biorock process, a low electric current is sent through steel structures under ocean water, which causes calcium carbonate to form. Polyps attached to Biorock structures use the energy they would have spent building calcium carbonate and instead devote it to growing and fighting disease. The Biorock reefs therefore grow faster than regular reefs.
Which cause = effect is correct?
Cause - Fishermen used dynamite and cyanide.
Effect - Biorock reefs grow more rapidly.
Cause - Fishermen used dynamite and cyanide.
Effect -. Coral reefs collapsed.
Cause - Biorock allows polyps to save energy.
Effect - Biorock reefs grow more rapidly.
Cause - Biorock allows polyps to save energy.
Effect - Coral reefs collapsed.
