What causes the seasons on earth? changes in the amount of energy produced in earth's core during different seasons. the earth moving closer to and further from the sun as it orbits. the tilt of the earth exposes different areas to direct sunlight as the earth orbits the sun. the amount of sunlight blocked by the moon changes as the earth orbits the sun.

The correct answer is - The tilt of the Earth exposes different ares to direct sunlight as the Earth orbits the Sun.

One of the biggest reasons why there's seasons on the Earth, is the Earth's tilt. In one part of the year, the Northern Hemisphere is the one that is more exposed to the Sun, and that is because of the tilting of the Earth, while the South Hemisphere in the same time is tilted away from the Sun. Because of this, the Northern Hemisphere experiences warmer weather, and it is summer, while in the Southern Hemisphere that has much less sunlight is much colder, and it is winter. This also goes the other way around in the other part of the year, where the Southern Hemisphere is tilted towards the Sun, while the Northern Hemisphere is tilted away from it.

the wrong statement is - c. a desert had more biodiversity than a marsh.

the deserts are one of the places of the planet where there's the least biodiversity. the reasons for that are the climate and the lack of food sources, which hampers both the number of the species that can survive in it, and the number of the individuals in the species itself.

the marshes, on the other hand, are places where there's perfect conditions for lots of organisms to thrive. the temperature is moderate and nice, the amount of water and the food sources are on a high level, so there's an abundance of both plant and animal life in them.
