Ocean Currents and Their Effects

The video tutorial covers lesson four of the sixth-grade ocean, atmosphere, and climate unit. It guides students through reading an article titled 'The Ocean in Motion,' discussing how ocean currents move and carry energy. The lesson includes instructions on accessing the article, either digitally or in print, and emphasizes the importance of taking notes and discussing with peers. The tutorial explains the concept of ocean currents, their role in energy transfer, and how they affect global climates. It also introduces the concept of gyres and their impact on ocean movement.

What is the main focus of the article 'The Ocean in Motion'?

• The history of ocean exploration

• How ocean currents affect climate

• The impact of pollution on marine life

• The role of oceans in the water cycle

What percentage of Earth's surface is covered by oceans?

• 50%

• 60%

• 71%

• 80%

What term do scientists use to describe ocean water flowing in a continuous path?

• Ocean wave

• Ocean current

• Ocean stream

• Ocean tide

How do ocean currents carry energy from the Sun?

• By reflecting sunlight

• By absorbing energy at the ocean surface

• By generating heat internally

• By moving towards the poles

What effect does a warm current have on the climate of a region?

• It causes storms

• It warms the region

• It has no effect

• It cools the region

Which current keeps Japan warmer than other places at the same latitude?

• A warm current from the equator

• A current from the Indian Ocean

• A cold current from Antarctica

• A current from the Atlantic Ocean

What is a gyre?

• A type of ocean wave

• A giant pattern of moving water

• A small whirlpool

• A deep-sea trench

How many main gyres are there in the world's oceans?

• Five

• Three

• Six

• Four

What causes the formation of gyres?

• The rotation of the Earth

• The melting of polar ice

• The movement of tectonic plates

• The gravitational pull of the moon

Why do ocean currents sometimes change direction?

• Because of the Earth's magnetic field

• Because of underwater volcanoes

• Due to changes in wind patterns

• As a result of human activity
