1.g. Students know how to determine the epicenter of an earthquake and know that the effects of an earthquake on any region vary, depending on the size of the earthquake, the distance of the region from the epicenter, the local geology, and the type of construction in the region. 6
Suggested Titles for California Science State Standard 1.g.

CA.2. Earth Science: Shaping Earth's Surface: Topography is reshaped by the weathering of rock and soil and by the transportation and deposition of sediment. As a basis for understanding this concept:

2.a. Students know water running downhill is the dominant process in shaping the landscape, including California's landscape. 11
Suggested Titles for California Science State Standard 2.a.

2.b. Students know rivers and streams are dynamic systems that erode, transport sediment, change course, and flood their banks in natural and recurring patterns. 10
Suggested Titles for California Science State Standard 2.b.

2.c. Students know beaches are dynamic systems in which the sand is supplied by rivers and moved along the coast by the action of waves. 11
Suggested Titles for California Science State Standard 2.c.

2.d. Students know earthquakes, volcanic eruptions, landslides, and floods change human and wildlife habitats. 33
Suggested Titles for California Science State Standard 2.d.

CA.3. Earth Science: Heat (Thermal Energy) (Physical Science): Heat moves in a predictable flow from warmer objects to cooler objects until all the objects are at the same temperature. As a basis for understanding this concept:

3.a. Students know energy can be carried from one place to another by heat flow or by waves, including water, light and sound waves, or by moving objects. 14
Suggested Titles for California Science State Standard 3.a.

3.b. Students know that when fuel is consumed, most of the energy released becomes heat energy. 21
Suggested Titles for California Science State Standard 3.b.

3.c. Students know heat flows in solids by conduction (which involves no flow of matter) and in fluids by conduction and by convection (which involves flow of matter). 8
Suggested Titles for California Science State Standard 3.c.

3.d. Students know heat energy is also transferred between objects by radiation (radiation can travel through space). 11
Suggested Titles for California Science State Standard 3.d.

CA.4. Earth Science: Energy in the Earth System: Many phenomena on Earth's surface are affected by the transfer of energy through radiation and convection currents. As a basis for understanding this concept:

4.a. Students know the sun is the major source of energy for phenomena on Earth's surface; it powers winds, ocean currents, and the water cycle. 8
Suggested Titles for California Science State Standard 4.a.

4.b. Students know solar energy reaches Earth through radiation, mostly in the form of visible light. 8
Suggested Titles for California Science State Standard 4.b.

4.c. Students know heat from Earth's interior reaches the surface primarily through convection. 5
Suggested Titles for California Science State Standard 4.c.

4.d. Students know convection currents distribute heat in the atmosphere and oceans. 6
Suggested Titles for California Science State Standard 4.d.

4.e. Students know differences in pressure, heat, air movement, and humidity result in changes of weather. 7
Suggested Titles for California Science State Standard 4.e.

CA.5. Earth Science: Ecology (Life Science): Organisms in ecosystems exchange energy and nutrients among themselves and with the environment. As a basis for understanding this concept:

5.a. Students know energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis and then from organism to organism through food webs.

5.b. Students know matter is transferred over time from one organism to others in the food web and between organisms and the physical environment.

5.c. Students know populations of organisms can be categorized by the functions they serve in an ecosystem. 13
Suggested Titles for California Science State Standard 5.c.

5.d. Students know different kinds of organisms may play similar ecological roles in similar biomes. 24
Suggested Titles for California Science State Standard 5.d.

5.e. Students know the number and types of organisms an ecosystem can support depends on the resources available and on abiotic factors, such as quantities of light and water, a range of temperatures, and soil composition. 23
Suggested Titles for California Science State Standard 5.e.

CA.6. Earth Science: Resources: Sources of energy and materials differ in amounts, distribution, usefulness, and the time required for their formation. As a basis for understanding this concept:

6.a. Students know the utility of energy sources is determined by factors that are involved in converting these sources to useful forms and the consequences of the conversion process. 28
Suggested Titles for California Science State Standard 6.a.

6.b. Students know different natural energy and material resources, including air, soil, rocks, minerals, petroleum, fresh water, wildlife, and forests, and know how to classify them as renewable or nonrenewable. 27
