v. biosphere

1. what is the biosphere?
2. show the relationship between individuals, populations, communities, and ecosystems
3. what is biodiversity and why is it important?

Explanation:

1. The atmosphere is a layer of gases surrounding a planet or other celestial body. It is held in place by the planet's gravity.
2. The four major parts of the atmosphere are the troposphere (closest to the Earth's surface, where weather occurs), stratosphere (contains the ozone layer), mesosphere (where meteors burn up), and thermosphere (hottest layer, extends into space).
3. Meteorology is the scientific study of the atmosphere, focusing on weather processes and forecasting.
4. Weather refers to short - term conditions in the atmosphere (e.g., temperature, precipitation, wind) at a specific place and time. Climate is the long - term average of weather patterns over a large area and extended period.
5. The geosphere is the solid part of the Earth, including rocks, minerals, and landforms.
6. The three major parts of the geosphere are the crust (the outermost solid shell), mantle (lies beneath the crust and is semi - molten), and core (the innermost part, divided into outer and inner core). They are differentiated by composition and physical state.
7. The Earth's core is composed mainly of iron and nickel. The outer core is liquid, while the inner core is solid due to high pressure.
8. The biosphere is the global sum of all ecosystems, the zone of life on Earth.
9. Individuals are single living organisms. A population is a group of individuals of the same species in a given area. A community is a group of different populations living and interacting in an area. An ecosystem includes the community and its physical environment.
10. Biodiversity is the variety of life in a particular habitat or ecosystem. It is important for ecosystem stability, provision of resources (e.g., food, medicine), and ecological services.

Answer:

1. A layer of gases surrounding a planet held by gravity.
2. Troposphere, stratosphere, mesosphere, thermosphere.
3. Scientific study of the atmosphere for weather processes and forecasting.
4. Weather is short - term, climate is long - term average.
5. The solid part of the Earth with rocks, minerals, landforms.
6. Crust, mantle, core; differentiated by composition and physical state.
7. Composed of iron and nickel; outer core is liquid, inner core is solid.
8. The global sum of all ecosystems, zone of life on Earth.
9. Individuals form populations, populations form communities, and communities with environment form ecosystems.
10. Variety of life; important for ecosystem stability, resources, and ecological services.
