True, the Himalayas formed due to continent-continent collision.
Answer: D. It can melt to a depth of a few meters in summer, then refreeze in winter.
Explanation:
Permafrost is ground which remains frozen for two or more years. Permafrost consists of soil, rock and sand fused together by ice. Mostly found in areas in high altitude, the Arctic, Antarctica, it is common in periglacial environments where temperatures are below freezing
.
The topmost layer of permafrost can melt in summer and refreeze in winter. This thawing and refreezing produces a ground pattern called columnar joints similar to the one formed when molten lava cools.
Answer:
Plants absorb water from the soil with the help of roots. It also absorbs minerals in organic form through root hairs. The water and minerals get transported by xylem vessels. ... - Another pressure called root pressure is also important as it is exerted by the root due to its metabolic activities.
Answer:
The water has left the system before if could be measured.
Explanation:
Some of the water has flowed quickly along as surface runoff and through the river channel. Scientists would then missed the chance to measure this rainfall. Some water will have been absorbed by nearby vegetation. The vegetation then releases the water in a vapor state, to the atmosphere. This process is known as transpiration. Heat in the atmosphere causes evaporation and the water never joins the soil of groundwater to be measured as part of the water table.
