nebula-is an interstellar cloud of dust, hydrogen gas, helium, and other ionized gas. terrestrial planet-a planet that is composed of silicate rocks and or metals. gas giant-a large planet the is not primarily composed of rock or other solid materials. planetesimal planet-solid objects thought to exist in protoplanetary disks and in debris disks satellite (moon)- a celestial body the orbits a planet or smaller body which is called it primary. asteroid- a class of small solar bodies that orbit the sun asteroid belt- the region i the solar system located roughly between the orbits of the planet mars and Jupiter. meteor- the visible path of a meteoroid the has entered earths atmosphere. meteoroid-a sand or boulder sized debris in the solar system meteorite-a natural object originating in outer space that survives impact with the earths surface comet- and icy small solar system body that when closes nought tot he sun displays a visible coma and sometimes also a tail. nucleus- a solid central part of a comet coma- a nebulous envelope around the nucleus of a comet. Kuiper belt-a region of the solar system around the planets existing from the orbit of neptune from the sun. Oort cloud- a hypothesized spherical could of comets which may lie roughly one light tear from the sun.

Directions: Work with a partner to explain one example of an **interaction between 2** of the [|earth systems] we discussed in class. (Lithosphere, Hydrosphere, Atmosphere, Biosphere). The systems are described in your notes for unit 1. Your job is to **type one paragraph** explaining ** how they interact ** and to ** include at least 1 supporting image **. Don't forget to make sure that the completed assignment is copied onto both of your wikis for grading purposes along with the title: **ASSIGNMENT 1: Earth Systems Interactions**.
 * ASSIGNMENT 1: Earth Systems Interactions**


 * example: Lithosphere and Hydrosphere**
 * [|Weathering]** is the breaking down of Earth's [|rocks], [|soils] and [|minerals] through direct contact with the planet's [|atmosphere] which contains water vapor (a part of Earth's hydrosphere). Through this process Earth's lithosphere is worn away slowly over time and sediments are laid down in new areas. These sediments will eventually form new rocks of Earth's crust. **Magma cooling:** Sometimes lava (magma that is pushed above Earth's surface comes into contact with ocean water (a part of the hydrosphere). This cool water rapidly cools the lava; turning it into the newest crustal rocks. (basalt in many cases).
