Answer:
Extrusive rocks are made on the surface of Earth from lava. Intrusive rocks are formed from magma that cools inside the crust of the planet.
Explanation:
Answer:
Terrestrial planets
Explanation:
There are two types of planets:
- The inner planets or terrestrial planets
- The outer planets or Jovian planets.
The outer planets are gas giants and are made of huge mounds of gases. These planets are Jupiter, Neptune, Uranus and Saturn. They all have satellites revolving round them.
The terrestrial planets are small rock masses. They are mercury, venus, earth and mars. Earth has one satellites and Mars has two satellites.
The asteroid belt seperates the Jovian and terrestrial planets. Beyond the Jovian planets lies the Kuiper Belt Objects or KBOs.
According to the continental drift theory, the supercontinent
Pangaea began to break up about 225-200 million years ago, eventually
fragmenting into the continents as we know them today.
Answer:
The hydrologic cycle is important because it is how water reaches plants, animals and us! Besides providing people, animals and plants with water, it also moves things like nutrients, pathogens and sediment in and out of aquatic ecosystems.
Explanation:
Ways in which the hydrologic cycle is affected
One of the ways that water moves through the cycle is through its ability to permeate, or soak, into the soil. There are four key areas that impact that part of the cycle:
changes in the ability of soil to soak up water through increases of impervious surfaces, like roads and buildings, and removal of forest cover;
water withdrawals or impoundments (such as through wells or dams)
filling depressional wetlands;
and altering stream flows and beds
The Coastal Lowlands include Florida's coasts and the Florida Keys. The Keys are a chain of small coral and limestone islands off the southern coast. The lowlands also include a vast wetland south of Lake Okeechobee. It is known as the Everglades. Often no higher than sea level, these areas flood quickly during storms. On the coasts, the land is primarily sand, with windblown dunes, sandbars, and lagoons.
