Convection in the water cycle is
when the air near the surface is heated, then rises taking heat with it
. Water vapour in the air gets cold and changes back into liquid, forming clouds. This is called condensation. Precipitation occurs when so much water has condensed that the air cannot hold it anymore.
What is convection in the water?
When water is heated, convection
causes the water at the bottom to expand and become lighter
. The heated molecules then rise to the top, which causes the cooler molecules to sink to the bottom. These cooler molecules then become heated. This process is repeated until all the water is the same temperature.
What are the 4 stages of water cycle?
There are four main stages in the water cycle. They are
evaporation, condensation, precipitation and collection
. Let’s look at each of these stages. Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas).
What are the 7 stages of the water cycle in order?
- Step 1: Evaporation. The water cycle begins with evaporation. …
- Step 2: Condensation. As water vaporizes into water vapor, it rises up in the atmosphere. …
- Step 3: Sublimation. …
- Step 4: Precipitation. …
- Step 5: Transpiration. …
- Step 6: Runoff. …
- Step 7: Infiltration.
Where does convection take place?
Convection takes place
in the atmosphere, in the oceans, and in Earth’s molten subcrustal asthenosphere
. Convective currents of air in the atmosphere are referred to as updrafts and downdrafts.
How does convection take place in fluid like water inside the pond?
Convection currents are set up in the fluid because the hotter part of the fluid is not as dense as the cooler part, so there is an upward buoyant force on the hotter fluid, making it rise while the cooler, denser, fluid sinks.
What are the 5 major processes of the water cycle?
Student Features. Many processes work together to keep Earth’s water moving in a cycle. There are five processes at work in the hydrologic cycle:
condensation, precipitation, infiltration, runoff, and evapotranspiration
. These occur simultaneously and, except for precipitation, continuously.
What are the 10 steps of the water cycle?
It can be studied by starting at any of the following processes:
evaporation, condensation, precipitation, interception, infiltration, percolation, transpiration, runoff, and storage
.
Where does the water cycle begin?
The water cycle has no starting point. But, we’ll begin in
the oceans
, since that is where most of Earth’s water exists. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air.
What are the 3 steps of the water cycle?
The water cycle is often taught as a simple circular cycle of
evaporation, condensation, and precipitation
.
Which comes first in the water cycle?
The first step of the water cycle is
evaporation
. About 85% of the water vapor in the air comes from water that evaporated from the oceans. The other 15% comes from evapotranspiration, which is a catch-all term for water that evaporates from over land.
What are 3 places that convection occurs on Earth?
- the geosphere – plate tectonics.
- the atmosphere – wind.
- the hydrosphere – ocean currents.
How does convection occur in the troposphere?
The uneven heating of the regions of the troposphere by the sun
( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe.
Which is an example of convection?
Everyday Examples of Convection
boiling water
– When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion.
In which of the does convection only occur in?
1 Answer. Convection only happens with
liquids and gases
.
How does a kettle heat water by convection?
The animation below shows heat transfer by convection in a kettle.
The water molecules at the bottom of the kettle gain heat energy from the flame and vibrate faster and move further apart
. Their density decreases and the hotter particle rise to the top of the kettle.
How do clouds form in the water cycle?
Clouds form
when the invisible water vapor in the air condenses into visible water droplets or ice crystals
. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.
What is evaporation in water cycle?
Evaporation is
the process by which water changes from a liquid to a gas or vapor
. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
How does water cycle process takes place?
The water cycle describes how
water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation
.
What are Earth’s water systems called?
A hydrosphere
is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet’s hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers.
What comes after the sun in the water cycle?
In both cases, the Sun’s energy causes the water to evaporate, and the water cycle continues.
Evaporation, condensation, and precipitation
are all parts of the water cycle.
