Answer the following question given this paragraph: All that magma and gas pushing upwards can make the volcano's slope begin to swell. Ground swelling may change the shape of a volcano or cause rock falls and landslides. Most of the time, the ground tilting is not visible. Scientists detect it by using tiltmeters, which are instruments that measure the angle of the slope of a volcano. Q: Which instruments are used to measure the angle of the slope of a volcano? Choices: - altimeter - compass - calipers - tiltmeters A:
tiltmeters
Answer the following question given this paragraph: Plants can get the energy they need for photosynthesis from either sunlight or artificial light. Q: Sunlight gives plants the energy they need for what? Choices: - respiration - absorption - glycolysis - photosynthesis A:
photosynthesis
Q: Answer the following question given this paragraph: Creep usually takes place where the ground freezes and thaws frequently. Soil and rock particles are lifted up when the ground freezes. When the ground thaws, the particles settle down again. Each time they settle down, they move a tiny bit farther down the slope because of gravity. Q: Creep, which usually takes place where the ground freezes and thaws frequently, involves movement of particles due to what force? Choices: - friction - wind - normal - gravity A:
A: gravity
Question: Answer the following question given this paragraph: Lymph vessels make up a circulatory system that is similar to the cardiovascular system, which you can read about in a previous concept. Lymph vessels are like blood vessels, except they move lymph instead of blood. Lymph is a yellowish liquid that leaks out of tiny blood vessels into spaces between cells in tissues. Where there is more inflammation, there is usually more lymph in tissues. This lymph may contain many pathogens. Q: Lymph vessels are like blood vessels, except they move what instead of blood? Choices: - marrow - sperm - air - lymph A:
Answer: lymph

Answer the following question given this paragraph: Because the ice is moving, glaciers have cracks called crevasses ( Figure below ). There is a large crevasse at the top of an alpine glacier called a bergshrund . Below the bergshrund, the ice is moving downhill. Above the bergshrund, the ice is stuck to the mountain. Q: The movement of ice causes glaciers to have cracks referred to as? Choices: - slides - fissures - anomalies - crevasses A:
**Answer**
crevasses

Answer the following question given this paragraph: All plants are adapted to live on land. Or are they? All living plants today have terrestrial ancestors, but some plants now live in the water. They have had to evolve new adaptations for their watery habitat. Q: Where do all plants come from? Choices: - phylogenetic ancestors - distant ancestors - cetacean ancestors - terrestrial ancestors A:
(Answer)
terrestrial ancestors
