Study Notes
Fossil Origin
- The word "fossil" originates from the Latin word "fossus", meaning "having been dug up".
Fossil Definition
- Fossils are the remains or traces of past organisms that have been naturally preserved.
Characteristics of Fossils
- Fossils can preserve an entire organism or just a part of one.
- Various parts can become fossils, including bones, shells, feathers, and leaves.
- Fossils can range in size from massive (like dinosaurs) to microscopically small (like bacteria).
Water Cycle
- The water cycle is a continuous process that circulates water between the Earth and the atmosphere.
Evaporation
- Evaporation is the process of converting liquid water into water vapor.
- It occurs on the surface of oceans, lakes, rivers, and the ground.
- Factors that influence evaporation include:
- Temperature
- Humidity
- Wind speed
- Solar radiation
Condensation
- Condensation is the process of converting water vapor back into liquid water.
- It occurs when air reaches its dew point, the temperature at which air becomes saturated with water vapor.
- Condensation forms clouds, fog, and dew.
Precipitation
- Precipitation is water that falls to the Earth's surface, including rain, snow, sleet, and hail.
- It forms when clouds become saturated with water and can no longer hold any more moisture.
- Types of precipitation include:
- Convectional precipitation (thunderstorms)
- Orographic precipitation (mountain-induced)
- Frontal precipitation (weather fronts)
Runoff
- Runoff is water that flows over the land surface, forming streams, rivers, and lakes.
- It occurs when the ground is saturated and can no longer absorb water.
- Factors that influence runoff include:
- Topography
- Land use (e.g., urbanization, deforestation)
- Soil type and permeability
Infiltration
- Infiltration is the process of water seeping into the soil and becoming groundwater.
- Factors that influence infiltration include:
- Soil type and permeability
- Vegetation cover
- Surface roughness
- Infiltrated water can recharge aquifers or be stored in the soil for plant use.
