Ques: Q: Extrusive igneous rocks are also called what? Read this paragraph and choose the correct option from the provided answers: Extrusive igneous rocks form above the surface. The lava cools quickly as it pours out onto the surface ( Figure below ). Extrusive igneous rocks cool much more rapidly than intrusive rocks. The rapid cooling time does not allow time for large crystals to form. So igneous extrusive rocks have smaller crystals than igneous intrusive rocks. Extrusive igneous rocks are also called volcanic rocks . Choices: - metamorphic - agates - magma minerals - volcanic rocks A:
Ans: volcanic rocks

Ques: Q: What is the study of structure, properties, and interactions of matter? Read this paragraph and choose the correct option from the provided answers: Chemistry is the study of the structure, properties, and interactions of matter. Important concepts in chemistry include physical changes, such as water freezing, and chemical reactions, such as fireworks exploding. Chemistry concepts can answer all the questions on the left page of the notebook in Figure below . Do you know the answers?. Choices: - petrology - biology - geology - chemistry A:
Ans: chemistry

Ques: Q: When you are walking on a sidewalk, what occurs between your shoes and the concrete each time you put down your foot? Read this paragraph and choose the correct option from the provided answers: Static friction acts on objects when they are resting on a surface. For example, if you are walking on a sidewalk, there is static friction between your shoes and the concrete each time you put down your foot (see Figure below ). Without this static friction, your feet would slip out from under you, making it difficult to walk. Static friction also allows you to sit in a chair without sliding to the floor. Can you think of other examples of static friction?. Choices: - movement - progress - grip - static friction A:
Ans: static friction

There are more than 100 different elements (92 of which occur naturally). The smallest particles of elements are atoms. Choices: - structures - arrangements - originals - elements A:
Ans:
elements
