Ocean currents can be triggered by ______________.

Ocean currents have_____________.

• By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate.

______ is defined as a movement of ocean water with a usual pattern.

Horizontal movement of ocean water due to wind on the surface of ocean is called

What is the effect of altitude on temperature? 

• Air at higher altitude is under less pressure than air at lower altitude because there is less weight of air above it.
• So it expands and cools.

________is the strongest evidence for climate change. 

The given image shows______________. 

_________is the Earth's slow vibration as it spins on its axis. 

• Eccentricity measures how much the shape of Earth's orbit departs from a perfect circle.
• The angle of Earth's axis of rotation is tilted as it travels around the Sun is known as obliquity.

_________explains the angle of tilt of the Earth's axis of rotation. 

The following image shows____________. 

• Precession is defined as the slow change in the direction of Earth's rotational axis.
• The angle of Earth's axis of rotation is tilted as it travels around the Sun is known as obliquity.

Changes of seasons are caused by____________. 

What change can be seen in living things as climate change? 

The Earth's orbit is __________ in shape. 

Earth's orbit is not circular or round but it's elliptical.

Earth orbits____________. 

Planets of solar system revolves around Sun.

What will happen if human impact of greenhouse gas is reduced? Changes in Earth's orbit, solar output, and other factors affect changes in the climate. Suppose if we removed the human impacts of greenhouse gas discharges what could be the climate doing currently on its own? 

• If all the factors were removed then Earth will cool down drastically.
• If human impacts of green house gases are increased and all other factors are workin then Earth will warm up.

__________is not associated with climate change.
