The biosphere is made up of the parts of Earth where life exists—all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosy...
The lithosphere is the terrestrial part of the biosphere. The deeper parts of the
lithosphere, known as the lower mantle and the core, do not support life,
other parts of lithosphere supports a variety of life from bacteria to large
mammals and trees. The weathering of the lithosphere crust forms soil, which
provides minerals and organic waste to support life. This solid, rocky crust is
composed of a number of different rocks that have been grouped into three
categories are metamorphic rocks, igneous rocks and sedimentary rocks.
Metamorphic rocks – Metamorphic rocks are formed by heat and pressure
from pre-existing rocks.
Igneous rocks – igneous rocks are formed by the cooling of hot molten rock
also known as magma. When the hot magma cools it begins to harden
meaning once it had fully cooled it create what is known to be an igneous rock
Sedimentary rocks – sedimentary rocks are formed from pre-existing rocks.
When rocks erode and mix with other dirt, clay and particles then settle
together the mix together to form a sedimentary rock
CYCLE OF ROCK FORMATION
ATMOSPHERE
The atmosphere is the gaseous envelope surrounding a planet. On Earth, it is
also called air. The lower regions of the atmosphere contain gases such as
oxygen and carbon dioxide that are essential for plant and animal respiration.
Birds, insects and other life can be found up to approximately 2,000 meters
above the earth’s surface. The atmosphere also plays critical roles in shaping
the biosphere by deflecting harmful radiation from the sun and determining
weather patterns.
HYDROSPHERE
The hydrosphere is the aquatic part of the biosphere. This includes oceans,
rivers, lakes and other bodies of water. The hydrosphere is always in motion as
seen through the movement and flow of water in rivers, streams and the
