EARTH & SPACE EXPLORATIONS

What is the innermost layer of the structure of the Sun?

• Radiative zone

• Convective zone

• Core

• Photosphere

Which of the following is a phenomenon that occurs on the surface of the Sun?

• Solar flare

• Aurora

• Elliptical orbit

• Magnetosphere

What is the main function of the Earth's magnetosphere?

• Causes the cycle of day and night

• Filters infrared radiation from the Sun

• Protects Earth from high-energy particles from solar wind

• Helps the process of photosynthesis

What is likely to happen if Earth does not have a magnetosphere?

• More rain falls

• Radio communication disruptions

• Earth becomes too hot like Venus

• Humans do not experience day and night

Which of the following is an effect of space weather on Earth?

• Thunderstorms

• Earthquakes

• Navigation system disruptions

• Volcanic eruptions

What phenomenon occurs when particles from solar wind interact with Earth's atmosphere?

• Aurora

• Solar flare

• Sunspots

• Solar cycle

The solar cycle typically occurs over a period of:

• 5 years

• 11 years

• 20 years

• 30 years

The increase in the number of sunspots is usually closely related to:

• Decrease in solar temperature

• Ozone layer damage

• Increase in coronal mass ejections and solar wind

• Slower rotation of the Sun

Copernicus's model of the solar system suggests that:

• Earth is the center of the universe

• The Sun is the center of the solar system

• Planetary orbits are triangular

• All planets orbit the Earth

What is Kepler's main contribution to understanding the solar system?

• Discovering the Sun as the center

• Creating the first telescope

• Proposing that planetary orbits are elliptical

• Building the heliocentric model
