Answer the following question given this paragraph: Large ocean currents can have a big impact on the climate of nearby coasts. The Gulf Stream, for example, carries warm water from near the equator up the eastern coast of North America. Look at the map in Figure below . It shows how the Gulf Stream warms both the water and land along the coast. Q: Which factor has a big impact on coastal climates? Choices: - ocean waves - tsunami - tide - large ocean currents A:
large ocean currents
Answer the following question given this paragraph: Carbonate minerals are often found where seas once covered the land. Some carbonate minerals are very common. Calcite contains calcium, carbon, and oxygen. Have you ever been in a limestone cave or seen a marble tile? Calcite is in both limestone and marble. Azurite and malachite are also carbonate minerals. They contain copper instead of calcium. They are not as common as calcite. Malachite and azurite are used in jewelry; as you can see, they are very colorful ( Figure below ). Q: What type of minerals are often found where seas once covered the land? Choices: - magnesium - crystals - sea salt - carbonate A:
carbonate
Q: Answer the following question given this paragraph: All life relies on a relatively narrow range of pH, or acidity. That's because protein structure and function are very sensitive to pH. Air pollution can cause precipitation to become acidic. Nitrogen and sulfur oxides, mainly from motor vehicle exhaust and coal burning, create acids when they combine with water in the air. The acids lower the pH of precipitation, forming acid rain . If acid rain falls on the ground, it may damage soil and soil organisms. If it falls on plants, it may kill them (see Figure below ). If it falls into lakes, it lowers the pH of the water and kills aquatic organisms. Q: When the ph of precipitation is lowered because of air pollution, what results? Choices: - abnormal rain - climate change - sleet - acid rain A:
A: acid rain
Question: Answer the following question given this paragraph: The location of an object in a frame of reference is called position. Q: The location of an object in a frame of reference is called what? Choices: - fact - change - marker - position A:
Answer: position

Answer the following question given this paragraph: Chemical changes are changes in the makeup and chemical properties of matter. An example of a chemical change is wood burning. Q: What are changes in makeup and chemical properties of matter called? Choices: - mineral changes - carbonate changes - radical changes - chemical changes A:
**Answer**
chemical changes
Q: Answer the following question given this paragraph: Collisions between gas particles and between particles and the container walls are elastic collisions . An elastic collision is one in which there is no overall loss of kinetic energy. Kinetic energy may be transferred from one particle to another during an elastic collision, but there is no change in the total energy of the colliding particles. Q: What sorts of collisions do not result in an overall loss of kinetic energy? Choices: - soft - static - powerful - elastic A:
A: elastic
