A person who use math, science and creativity to solve problems in the environment.
anything designed to solve a problem
species that serve as early warnings that an ecosystem is being damaged
A group of parts that work together in a meaningful way
all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds.
all the living things on Earth: plants, animals and people
A thin layer of gases surrounding Earth
the solid part of the earth consisting of the crust and outer mantle
It includes mountains, continents and the land under the ocean.
What is included in the hydrosphere?
oceans, bays seas, rivers, lakes, glaciers, waterfalls, ponds, reservoirs, swamps, snow, water vapor, rain, sleet, ground water, run off, ...
The change of a substance from a liquid to a gas
The change of state from a gas to a liquid
Any form of water that falls from clouds and reaches Earth's surface.
the process by which water on the ground surface enters the soil
Evaporation of water from the leaves of a plant
water that flows over the ground surface rather than soaking into the ground
The Stages of the Water Cycle
evaporation, transpiration, condensation, transportation, precipitation, infiltration, run off
Why are there more severe rain storms?
The Earth's oceans have been heating up due to climate change. Warmer water evaporates faster than cooler water. More evaporation means more precipitation. So, as Earth heats up, some areas will get more rain.
How does the hydrosphere affect the geosphere?
Rain, rivers and the ocean erode land. They wash away the soil and sand. These parts of the geosphere may be deposited in a new area. Glaciers erode the land when they slide downward. Over long periods of time they can carve out large valleys. Glaciers move soil and rocks. Glaciers wear away mountains. Rain can cause mudslides and can weather rock.
The breaking down of rocks and other materials on the Earth's surface.
The process by which wind, water, ice, or gravity transports soil and sediment from one location to another
rain shadow effect
Precipitation falls on the windward side of a mountain range, resulting in lush vegetation & a warm, moist climate on one side, but a desert area on the leeward side.
How does the geosphere affect the hydrosphere?
The geosphere can block rain clouds causing one side of a mountain side to receive rain and produce lush vegetation and the other side to remain dry and produce desert-like conditions. An earthquake under the ocean can cause a tsunami if one piece of land rises up, and the other piece of land sinks down.
How does the hydrosphere affect the atmosphere?
The ocean absorbs a great deal of the sun's heat. Icecaps and glaciers reflect much of the sun's heat because they are white. They help keep the Earth from overheating. As this ice melts, the Earth will absorb more and more heat.
the process of sending the sun's rays back up into the atmosphere
Reflectivity occurs when the white snow on the glaciers reflects the sun's rays back into the atmosphere.
How does the atmosphere affect the hydrosphere?
1) The atmosphere absorbs water through evaporation. 2)
The atmosphere protects the Earth from the sun's ultraviolet rays, thereby keeping the oceans cooler and enabling water to exist on Earth. 3) The ocean absorbs carbon dioxide from the atmosphere. For this reason, we say the ocean is a "carbon sink". 4) The extra carbon dioxide in the ocean is making the ocean water more acidic. We call this "ocean acidification". Ocean acidification is harming the plants and animals in the ocean. Acidic water kills seaweed. Acidic water makes lobster shells softer. This makes the animal more likely to become diseased.
a forest, ocean, or other natural environment viewed in terms of its ability to absorb carbon dioxide from the atmosphere.
when CO2 dissolves in seawater, it reacts with water to form carbonic acid, which lowers ocean pH
What is the 70:30 ratio?
70% of the Earth is covered with water. 30% of the Earth is covered by land.
What is the distribution of water on Earth?
97% salt water in oceans
about 2% - ice caps and glaciers
less than 1% - freshwater
sea level rise
Sea level rise is the term that is used for the rising levels of the ocean. The ocean level has been rising faster in the past 100+ years because our planet is warming and glaciers are melting and adding to the ocean's water level.
ice core samples
cores removed from ice sheets to reconstruct the climate record over hundred of thousands of years
