Which of the following is a type of igneous rock? granite Without the atmosphere, the surface of the Earth would be colder Which method of heat travel only takes place in gases and liquids? convection Which of the following most clearly illustrates the transfer of energy through radiation? heating of Earth's surface The underground region in which all the pores are filled with water is called the zone of saturation. High, feathery clouds made of ice crystals are called cirrus Thundershowers usually accompany the arrival of what kind of front? cold Based on the following diagram of Earth, people in the Northern Hemisphere are experiencing which of the following seasons? summer How do inner and outer planets in our solar system differ? Inner planets are small and rocky, whereas outer planets are large and gaseous. The Russian space program has made significant contributions to space exploration including putting the first woman in space. The Hubble telescope has exhibited great clarity. This is a result of the Hubble's placement outside of the Earth's atmosphere.

Studying a list of planets and their distance from the sun Which graph with a student used to display data that shows how one variable changes in response to another variable? Line Graph what would be the best practice to teach students what animal a barn owl consumes? Students will research about barn owls in teams Student A is struggling to understand the fourth grade concept of force and motion. The teacher pairs student A with student B who understand the concept. Together the students work in the science center to complete a guided activity incorporating various materials.

This statement is a (an) Hypothesis Which of the following types of telescopes use lenses to form the primary image? Refracting A group of fifth grade students designed an experiment to determine the effects of fertilizer on plant growth. They obtained 10 small pots and placed equal amounts of potting soil in each pot. They planted seeds in each pot and placed the pots in the same sunny area. Each day they watered the plants with an equal amount of water. They also added equal amounts of fertilizer to the plants. Each week they measured the height of the plants. After four weeks, the plants had grown and average of 6 inches and the students concluded that the fertilizer had a positive affect on plant growth. Which of the following would best improve the students experiment so that their conclusions are plausible and valid? Adding a control group Why are geologist important to the safety of transportation systems such as tunnels and bridges?
