What causes the seasons pick the most important factor?
The seasons are caused by the tilt of the Earth’s rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the “ecliptic plane” (the imaginary surface formed by it’s almost-cicular path around the sun).
What two weather conditions change with seasons?
Seasonal effects Seasonal changes in precipitation and temperature affect soil moisture, evaporation rates, river flows, lake levels, and snow cover. Leaves fall and plants wither as cold and dry seasons approach. These changes in vegetation affect the type and amount of food available for humans and other organisms.
Where is the Earth now six months later?
Six months later, the Earth is leaning in the opposite direction. The Earth’s tilt causes the Southern Hemisphere (SH) to lean towards the Sun during SH summer. Meanwhile, it is winter in the Northern Hemisphere (NH) which leans away from the Sun. Six months later, the situation is reversed.
Which factor has the biggest impact on Earth’s seasons?
The tilt of the Earth has the biggest impact on the seasons. Let’s find out why. Here is the Earth when it is winter for each hemisphere. Look at the position and tilt of the Earth.
What would Earth be like without seasons?
In a world without seasons, there wouldn’t even be wheat. According to Don Attwood, an ecological anthropologist at McGill University in Montreal, humans would probably never have advanced past a state of living in small, scattered settlements, scrounging for survival and often dying of horrific insect-borne diseases.
How do seasons affect our lives?

How does changing weather affect us?
A warmer climate is expected to increase the risk of illnesses and death from extreme heat and poor air quality. Climate change will likely increase the frequency and strength of extreme events (such as floods, droughts, and storms) that threaten human health and safety.
Does changing weather make you sick?
Most people would agree, sudden weather changes can make you feel under the weather. It can’t actually make you sick, you need to be exposed to the actual bacteria or viruses. But it can weaken your immune system and make you more susceptible to those germs.
Does global warming cause natural disasters?
With increasing global surface temperatures the possibility of more droughts and increased intensity of storms will likely occur. As more water vapor is evaporated into the atmosphere it becomes fuel for more powerful storms to develop.
Why is disaster increasing?
However, the main contribution to the upward trend of the losses caused by natural catastrophes comes from socio-economic/demographic factors such as population growth, ongoing urbanization and increasing values being exposed.
