6th science BM2 Review

Front

What are trade winds?

Back

Trade winds are winds that blow from the east towards the west in the tropics, created by the heating of air at the equator that rises and moves toward the poles, while cooler air moves in from the north.

What is the primary source of freshwater?

Back

Freshwater is found in glaciers, lakes, rivers, and underground aquifers, but oceans are least likely to be a source of freshwater due to their high salt content.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere, which allows sunlight in but prevents some of the heat from escaping.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions in a specific place at a specific time, while climate is the long-term average of weather patterns in a particular area.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water evaporates from the Earth's surface, condenses in the atmosphere, and precipitates back to the surface as rain or snow.

Front

What are polar easterlies?

Back

Polar easterlies are cold winds that blow from the east near the poles, created by the sinking of cold air and the rotation of the Earth.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight warming the Earth.

Front

What is the role of the Sun in Earth's weather?

Back

The Sun provides energy that heats the Earth's surface, driving atmospheric circulation and influencing weather patterns.
